PENNSYLVANIA: Harris 51%, Trump 45%, Stein 1%, Oliver 1%

MICHIGAN: Harris 50%, Trump 45%, Stein 2%

WISCONSIN: Harris 48%, Trump 47%, Stein 1%

One week after the presidential debate between Vice President Kamala Harris and former President Donald Trump, the 2024 presidential race in three critical battleground states shows Harris leading Trump in Pennsylvania, holding a slight lead in Michigan, and the two candidates essentially tied in Wisconsin, according to Quinnipiac (KWIN-uh-pea-ack) University polls of likely voters in each of the states released today.

HARRIS VS. TRUMP: THE ISSUES

The race is competitive on most issues. Likely voters were asked who they think would do a better job handling five issues...

The economy:

PA: 50 percent say Trump, while 48 percent say Harris;

MI: 50 percent say Trump, while 48 percent say Harris;

WI: 51 percent say Trump, while 47 percent say Harris.

Immigration:

PA: 50 percent say Trump, while 46 percent say Harris;

MI: 49 percent say Trump, while 48 percent say Harris;

WI: 52 percent say Trump, while 45 percent say Harris.

Preserving democracy in the United States:

PA: 45 percent say Trump, while 52 percent say Harris;

MI: 45 percent say Trump, while 51 percent say Harris;

WI: 47 percent say Trump, while 50 percent say Harris.

Abortion:

PA: 38 percent say Trump, while 57 percent say Harris;

MI: 42 percent say Trump, while 53 percent say Harris;

WI: 40 percent say Trump, while 53 percent say Harris.

A crisis that put the country at great risk:

PA: 47 percent say Trump, while 49 percent say Harris;

MI: 47 percent say Trump, while 51 percent say Harris;

WI: 48 percent say Trump, while 49 percent say Harris.

"Three crucial swing states wave a red flag at the Trump campaign. The GOP's most 'go to' attack strategies against Democrats on immigration and the economy may be losing momentum. Likely voters now see little daylight, in most cases, between Harris and Trump on who can best handle those key issues," said Quinnipiac University Polling Analyst Tim Malloy.

PENNSYLVANIA: PRESIDENTIAL RACE

In Pennsylvania, viewed as a must-win state in the path to the White House, Harris receives 51 percent support among likely voters, Trump receives 45 percent support, and Green Party candidate Jill Stein and Libertarian Party candidate Chase Oliver each receive 1 percent support. This compares to a Quinnipiac University poll of likely voters in Pennsylvania on August 14 when Harris received 48 percent support and Trump received 45 percent support.

Democrats 95 - 4 percent back Harris, while Republicans 91 - 7 percent back Trump. Among independents, 48 percent back Harris, while 43 percent back Trump.

In a hypothetical two-way race between Harris and Trump, Harris has a slight lead over Trump 51 - 46 percent. In August, Harris received 50 percent support and Trump received 47 percent support.

PENNSYLVANIA: ENTHUSIASM

Seventy percent of likely voters supporting Harris say they are very enthusiastic about supporting her, compared to 66 percent in August.

Seventy-three percent of likely voters supporting Trump say they are very enthusiastic about supporting him, compared to 70 percent in August.

PENNSYLVANIA: FAVORABILITY RATINGS

Forty-eight percent of likely voters have a favorable opinion of Harris, while 43 percent have an unfavorable opinion of her, compared to August when 46 percent had a favorable opinion of her and 48 percent had an unfavorable opinion of her.

Forty-four percent of likely voters have a favorable opinion of Trump, while 53 percent have an unfavorable opinion of him, unchanged from August.

"Favorability, that catch-all for what voters think about candidates from policy to personality to promise, tips Harris' way since we last polled Pennsylvanians. A post-debate shift, though small, suggests voters are warming up to her," added Malloy.

PENNSYLVANIA: U.S. SENATE RACE

Incumbent Democratic Senator Bob Casey leads Republican challenger David McCormick 52 - 43 percent, essentially unchanged from August.

In today's poll, Democrats (96 - 3 percent) and independents (51 - 41 percent) back Casey, while Republicans (89 - 7 percent) back McCormick.

MICHIGAN: PRESIDENTIAL RACE

In Michigan, Harris receives 50 percent support among likely voters, Trump receives 45 percent support, and Green Party candidate Jill Stein receives 2 percent support. All other listed third-party candidates receive less than 1 percent support.

In a hypothetical two-way race between Harris and Trump, Harris receives 51 percent support and Trump receives 46 percent support.

"With a gender gap as wide as Lake Michigan, Harris leads Trump by about 20 percentage points among women and Trump leads Harris among men by half that," added Malloy.

MICHIGAN: ENTHUSIASM

Seventy-nine percent of likely voters supporting Harris say they are very enthusiastic about supporting her.

Eighty-three percent of likely voters supporting Trump say they are very enthusiastic about supporting him.

"Ten electoral votes hang in the balance in a state that went Biden's way by a minuscule 0.63 percent in 2020. Might 2024 also be decided by the narrowest of margins? It sure looks that way," added Malloy.

WISCONSIN: ENTHUSIASM
