Kamala Harris Gets Worrying Sign in Bellwether Pennsylvania County: Poll

Vice President Kamala Harris received a worrying sign in a bellwether county in the battleground state of Pennsylvania, according to a poll published on Friday.

Election Day is only three days away and tens of millions of voters have already cast their ballots early in a tight race between Harris, the Democratic presidential nominee, and former President Donald Trump , the Republican presidential nominee.

Pennsylvania is key to win because it has 19 electoral votes, the most out of all seven swing states. It is also one of the swing states that has the smallest margin of voter support between the two candidates.

A new USA Today/Suffolk University poll has Harris and Trump tied with 49 percent of the vote each. The poll was conducted from October 27 to 30, surveyed 500 likely Pennsylvania voters and has a margin of error of 4.4 percentage points.

However, Harris has a worrying sign when looking at the bellwether Northampton County. A bellwether region is a place where the election results typically reflect how the overall electorate votes.

Friday's poll had Trump slightly leading Harris in Northampton County (50 to 48 percent). However, the two candidates are tied with 48 percent each in another Pennsylvania bellwether, Erie County. The polls surveyed 300 likely voters in each county. The polls' results fall within their margin of error of 5.65 percentage points.

In September, Harris was leading Trump in Erie and Northampton counties—both where outcomes have correctly predicted the overall winner of presidential elections since 2008.

Polls released then by USA Today and Suffolk University showed Trump trailing Harris by 5 points in Northampton County and 4 percentage points in Erie County.
