Pennsylvania Presidential Race Updates

Tuesday, Nov. 3: Joe Biden's lead in Pennsylvania has remained about the same since last week, according to the betting market, but Donald Trump's chances have actually worsened.

Betfair has reduced the hold on this market — essentially giving the consumer a more fair price — by keeping Biden at -227 and moving Trump up to +175.

Pennsylvania is arguably the most important state in the election, depending on what other dominoes fall.

Friday, Oct. 30: Joe Biden's -227 odds give him a 64.6% implied probability over Donald Trump (+163; 35.4%) to win Pennsylvania, which delivered the President his closest victory in 2016.

Biden also leads Trump in FiveThirtyEight's average of polls as well as wins 85 out of every 100 simulations in Nate Silver's model.

Friday, Oct. 16: With less than three weeks until Election Day, the betting market gives Joe Biden a 73.7% vs. 26.3% edge in implied probability over Donald Trump to win Pennsylvania — one of the most critical swing states.

FiveThirtyEight's forecast, which simulates the election 40,000 times, projects Biden to win 87 out of every 100 times and Trump only 13 out of every 100 times. The site's average of polls additionally gives the former Vice President a 50.7% to 43.9% edge over the President.

Although the betting odds and FiveThirtyEight give Biden a favorable projection, it's expected to be another close and pivotal result this November. With 20 of the 538 total electoral votes, Pennsylvania is tied with Illinois for the fourth-most electoral votes in the country, making it historically among the most important battleground states in presidential elections.

Pennsylvania delivered Trump his narrowest victory among the 50 states in the 2016 election, edging out Democratic nominee Hillary Clinton by only 0.72%. Trump ended up winning 304 of the electoral college votes compared to Clinton's 227.
