Pennsylvania Election Odds — 2026 Live Betting Odds & Voting History

Is Pennsylvania a red state or a blue state?

Pennsylvania is a swing state, with a slight Democratic lean at the presidential level and a Republican advantage downballot. The state has voted Democratic in seven of the last nine presidential elections, but the margins are routinely the tightest in the country. Trump carried Pennsylvania by 1.7 points in 2024 after losing it by 1.2 in 2020 and winning it by 0.7 in 2016. Cook PVI rates Pennsylvania R+2, technically tilting Republican but functionally the definition of a tossup. No state has been more decisive in modern presidential elections.

The downballot picture is more Republican than the top of the ticket suggests. Republicans hold both chambers of the state legislature, won the U.S. Senate seat in 2022 (John Fetterman, though Fetterman has since moved sharply toward the center), and have held the other Senate seat under Republican Dave McCormick since 2025. Democrats control the governorship under Josh Shapiro, who won by 15 points in 2022 and is favored to win reelection in November 2026. The state's Cook PVI of R+2 reflects this split: federal races break Democratic, state races break Republican.

Pennsylvania's voting pattern is driven by a famous demographic divide. Philadelphia and its inner suburbs (Montgomery, Delaware, Bucks, Chester counties) vote heavily Democratic. Pittsburgh and Allegheny County have moved Democratic over the past two decades. The rest of the state, particularly the rural T-shaped region running from Erie down through central Pennsylvania, votes heavily Republican. The 2024 election came down to whether Trump could run up his margins in those rural counties faster than Democrats could expand theirs in the Philadelphia suburbs. He did, by 1.7 points.

The state has been at the center of every modern presidential election. Trump won it in 2016 by 44,000 votes, Biden won it in 2020 by 80,000 votes, and Trump won it in 2024 by 120,000 votes. No state has produced more election-night drama in the past three cycles. Pennsylvania has 19 electoral votes through 2030, the fifth-most in the country, and is essentially a must-win for any plausible path to 270.

Will Pennsylvania stay competitive? Yes, for the foreseeable future. The demographic forces pulling the state in both directions, suburban realignment toward Democrats and rural realignment toward Republicans, are running close to even. Polymarket already prices Pennsylvania as one of the most competitive states for 2028, and Governor Shapiro's potential presidential run could pull it slightly back toward Democrats.

Pennsylvania governor betting odds

Shapiro is running with structural advantages no Pennsylvania incumbent has enjoyed in decades. His 60% job approval rating in Quinnipiac's October 2025 poll is the highest of his governorship. He raised $23 million in 2025 and had $30 million cash on hand at the start of 2026, against Garrity's $1.5 million raised and $1 million cash. He has privately told donors he aims for $90-100 million total — which would break the Pennsylvania record he himself set in 2022. In head-to-head polling, Shapiro leads Garrity 55-39.

Garrity's pitch is that Shapiro is more interested in running for president than governing Pennsylvania. She has the strongest fundraising record of any Pennsylvania GOP statewide candidate in years, having posted the highest vote total of any 2024 statewide office in her treasurer re-election. Garrity is widely viewed as a more formidable candidate than Mastriano was, but Republicans privately concede the race is uphill given Shapiro's standing. The general is November 3, 2026.

Pennsylvania presidential election betting odds

Pennsylvania is the most important state in presidential election. Trump won it by 0.7 points in 2016, Biden by 1.2 points in 2020, and Trump by 1.7 points in 2024. The 2024 result made Pennsylvania the tipping-point state — the state that, if it had flipped to Harris, would have shifted the Electoral College outcome with margin to spare. Pennsylvania's Cook PVI of R+1 reflects this: it is roughly even with the nation overall, voting only marginally more Republican than the national popular vote.

The state's centrality to 2028 is already shaping markets. Josh Shapiro is one of the leading Democratic presidential prospects, and his 2026 margin against Garrity will be read as a leading indicator. An October 2025 Quinnipiac poll testing a hypothetical 2028 Shapiro-Vance matchup had Shapiro winning Pennsylvania 53-43. On the Republican side, Senator Dave McCormick — who flipped the state's other Senate seat in 2024 by 0.24 points — is occasionally mentioned in long-shot 2028 markets, but his focus appears to be his own Senate work and not a presidential run.

Pennsylvania senate betting odds

Neither Pennsylvania Senate seat is on the 2026 ballot. Senator John Fetterman (D), elected in 2022 by 5 points over Mehmet Oz, is next up in 2028. Senator Dave McCormick (R), who defeated Bob Casey Jr. by 16,000 votes in 2024 to flip Pennsylvania's second Senate seat to Republicans, is next up in 2030. Pennsylvania has the only true split Senate delegation among the swing states.

Pennsylvania Senate markets in 2026 are limited to early 2028 speculation. Fetterman has drawn primary interest from his left after a series of disagreements with the Democratic caucus on Israel, immigration, and other issues; some markets price the probability of a credible primary challenge to him in 2028. McCormick is universally expected to seek re-election in 2030. See all of the senate seats up for election here.

Pennsylvania house betting odds

Pennsylvania has 17 seats in the house of representatives, currently split 10 Republicans to 7 Democrats. Pennsylvania's congressional map was drawn by the state Supreme Court in 2018 and modified by the Legislature in 2021 — both processes produced a map that is competitive in a way most state maps are not, with four genuine swing districts that have changed party hands in the past three cycles. Democrats settled their nominees for those four target races in the May 19, 2026 primary, with Gov. Shapiro endorsing every winner.

• PA-1 (Bucks County): Bob Harvie, the Bucks County Commissioner, won the Democratic primary against Lucia Simonelli. He faces five-term Republican Brian Fitzpatrick, the last northeastern Republican holdout in suburban Philadelphia.
• PA-7 (Lehigh Valley): Bob Brooks, a former firefighter and union president, won a four-way Democratic primary. He faces freshman Republican Ryan Mackenzie, who narrowly flipped the seat from Susan Wild in 2024.
• PA-8 (Scranton / Wilkes-Barre): Scranton Mayor Paige Cognetti was uncontested for the Democratic nomination. She faces freshman Republican Rob Bresnahan, who narrowly flipped the seat from Matt Cartwright in 2024. Bresnahan has faced criticism over stock trading as a member of Congress, which Cognetti has made central to her campaign.
• PA-10 (Harrisburg / York): Former WGAL news anchor Janelle Stelson won the Democratic primary against Dauphin County Commissioner Justin Douglas. This is a rematch of 2024, when Stelson lost to six-term Republican Scott Perry by 1.5 points. Perry's role in attempts to overturn the 2020 election results has been a renewed focus of the race.

Republicans are defending all four with the slim 220-215 House majority depending on Pennsylvania's outcomes more than almost any other state. A separate Democratic primary fight in PA-3 (Philadelphia) was won by state Rep. Chris Rabb after retiring Rep. Dwight Evans's open seat drew an eight-candidate field. The district is solid Democratic.

No mid-decade redistricting is contemplated in Pennsylvania. The state's redistricting process makes single-party redraws procedurally difficult, and neither party has moved to start one. The November 3 general election will be run on the existing 2021 map.
