(The Hill) — Vice President Harris is up 4 points on former President Trump in three battleground states with less than three months left until the election, according to new polling from The New York Times/Siena College.

The survey, published Saturday morning, found that Harris has taken the lead over the former president in Michigan, Wisconsin and Pennsylvania, garnering 50 percent support to Trump’s 46 percent in the hypothetical matchup.

Harris’s numbers mark a significant improvement to former President Biden’s in the same swing states.

In two separate NYT/Siena surveys earlier this year, Biden garnered 45 percent support to Trump’s 48 percent in Pennsylvania. The poll from April and early May, however, showed the president leading his GOP rival in Michigan and Wisconsin (47 percent to 46 percent).

Harris has garnered large amounts of enthusiasm and support from Democrats since she began her presidential campaign last month after President Biden stepped out of the 2024 race for the White House. She announced her running mate, Minnesota Gov. Tim Walz (D), earlier this week.

This week, Harris has made multiple campaign stops in key battleground states like Michigan and Wisconsin. Her campaign has said that 14,000 people attended her rally in Philadelphia on Tuesday and 15,000 attended another in Detroit on Wednesday night.

Asked how satisfied voters were with their party’s nominee, most respondents in the survey gave a positive answer.

Broken down by party, Democrats were more likely than Republicans to say they were satisfied with their nominee — 87 percent to 79 percent, respectively. Roughly 12 percent of Democrats and 19 percent of Republican respondents said they were unsatisfied, per the poll.

About 60 percent of independent voters said they were satisfied, compared to 37 percent who said the opposite, the survey found.

The Times/Siena polls were conducted between Aug. 5-8 with 619 registered voters in Michigan and 661 in Wisconsin. The Pennsylvania survey was conducted between Aug. 6-9 with 693 registered voters.

The margin of error for each survey was plus or minus 4.8 percentage points in Michigan, plus or minus 4.3 percentage points in Wisconsin and plus or minus 4.2 percentage points in Pennsylvania.

The Hill/Decision Desk HQ’s national polling index shows Trump leading Harris nationally by 0.02 percent — 47.4 percent to 47.2 percent — based on over 100 surveys.
