Poll: Harris up in Pennsylvania, Trump leads in Arizona

Former President Donald Trump is leading by six points in Arizona, while Vice President Kamala Harris leads by four points in Pennsylvania, according to new polls from the New York Times, Philadelphia Inquirer and Siena College .

The poll of more than 1,600 voters across two crucial swing states illustrates the deadlocked nature of the presidential contest, as both candidates race to convince a tiny sliver of undecided voters to choose them.

Trump's strength in Arizona has been buoyed by voters' concerns about the economy, while Harris has maintained an edge in Pennsylvania largely due to her stance on abortion. Voters in the Keystone State said they trusted her over Trump to handle the issue of abortion by 20 percentage points.

Harris' lead in Pennsylvania is within the margin of error, but mirrors a consistent small lead in polling for months. The state is seen as the most important battleground state in this election with 19 electoral votes.

Trump has an 11-point lead over Harris in Pennsylvania on the economy, which grew from a 4-point lead in the Times' September poll. His six-point lead in Arizona is consistent with previous polls. He leads on the economy in Arizona by 15 points.

Both campaigns are spending big in Pennsylvania in the final weeks of the race. Harris, Trump and outside groups have spent around $350 million in television ads in the state and are frequently visiting for campaign stops.
