(The Hill) — Vice President Harris has a 3-point edge over former President Trump in battleground Pennsylvania, according to new polling. The New York Times/Philadelphia Inquirer/Siena College survey, released Saturday, shows Harris leading Trump 50 percent to 47 percent among likely voters in the Keystone State. Pollsters and analysts say Pennsylvania more than any other state will decide the winner of the election, now less than a month away. The GOP nominee, however, is ahead in Arizona, another critical swing state, 51 percent to Harris's 46 percent. When asked how likely respondents are to vote in November, the vast majority, 73 percent, said they were "almost certain" they would cast their ballot in the election. Survey respondents chose the economy, abortion and immigration as top issues that could affect their vote. When asked, regardless of preference, who would do a better job to address the issue, Trump bests Harris on economy and immigration, but the vice president is ahead on abortion. The former president garnered 54 percent support on handling the economy, compared to Harris's 43 percent. On immigration, he received 55 percent to her 42 percent, according to the survey. On the issue of abortion and reproductive rights, the vice president bested her GOP rival by double digits — 56 percent to 38 percent, the data shows. As the election nears, The Hill/Decision Desk HQ's polling index shows Harris narrowly leading Trump in Pennsylvania with 48.6 percent support to his 48 percent. In the Grand Canyon State, the former president outpaces the Democratic nominee by a slightly larger, but still very narrow, margin, 48.5 percent to 47.6 percent, the index found. The Times/Inquirer/Siena poll, conducted from Oct. 7-10, surveyed 857 voters in Pennsylvania and 808 voters in Arizona. The margin of error was 3.8 percentage points for Pennsylvania and 3.9 percentage points for Arizona.
