Harris vs. Trump: New presidential swing state poll has Harris up 8%

Amid a tightening race for president, Vice President Kamala Harris has opened up a significant lead over former President Donald Trump in a key swing state.

In a poll released Friday, Bullfinch Group revealed data from a poll of 600 voters each in Michigan, Wisconsin and Pennsylvania.

Overall, the data showed a close race, but voters in Michigan revealed a clear preference for Harris by a margin of 53% to 45% in a head-to-head matchup between Harris and Trump, and a margin of 51% to 43% when third party candidates are included.

In both cases, Harris held an 8% lead.

The poll, which was taken over the course of Oct. 11-18, had a margin of error of plus-or-minus 4%.

The race is much closer in Wisconsin and Pennsylvania, the poll revealed.

In Wisconsin, voters preferred Harris by 3% (50%-47%) in a head-to-head matchup, and chose Harris by 2% (48%-46%) when third party candidates were included.

Pennsylvania marked the closest state in the survey. Voters there were tied at 49% apiece in a head-to-head matching, and gave Harris a slight 49%-48% edge when third party candidates were included.

The poll also surveyed respondents on how they would vote in their states' respective U.S. Senate races. In all cases, the Democrat was ahead by a wider margin than in the presidential race.

In Michigan, Democrat Elissa Slotkin was ahead of Republican Mike Rogers by 9%, a margin of 51% to 42%. In Pennsylvania, incumbent Democrat Bob Casey Jr. was ahead of Republican challenger Dave McCormick by a 7% margin of 50% to 43%.

Wisconsin was the closest Senate race polled. Democratic incumbent Tammy Baldwin was ahead of Republican challenger Eric Hovde by a margin of 49% to 45%, or 4% total.
