Swing state poll shows Trump trailing in two crucial battlegrounds while a third is too close to call

Former President Donald Trump is trailing Vice President Kamala Harris in two crucial battleground states, while a third state remains a toss-up. 

A Quinnipiac University poll released Wednesday shows Harris ahead of Trump in Pennsylvania and Michigan and the rivals statistically tied in Wisconsin. 

Trump won all three so-called blue wall states over Democrat Hillary Clinton in 2016, delivering him an Electoral College victory. 

In 2020, President Joe Biden flipped the three states back to the Democratic column. 

Harris now has a six-point lead in Pennsylvania - 51 percent to 45 percent - with Green Party hopeful Jill Stein and Libertarian Party candidate Chase Oliver garnering 1 percent each.

The three blue wall states handed former President Donald Trump a victory over Hillary Clinton in 2016, but President Joe Biden won them back for Democrats four years later

The margin of error in Pennsylvania is plus or minus 2.7 percent. 

In Michigan, Harris leads Trump by five points - 50 percent to 45 percent - with Stein receiving 2 percent of the vote. 

Her lead is narrowly outside the plus or minus 3.3 percent margin of error. 

In Wisconsin, Harris leads by 1 point -  48 percent to Trumps 47 percent - with Stein recieving 1 percent of the vote. 

That poll had a plus or minus 3 percent margin of error. 

By narrow margins, voters in the three states say Trump is the better leader on the economy and immigration but Harris is the far-and-away leader on the issue of abortion. 

In Pennsylvania, 57 percent say Harris would do a better job handling the issue of abortion, compared to 38 percent who said Trump. 

In Michigan its 53 percent for Harris and 42 percent for Trump and in Wisconsin 53 percent also said Harris, while 40 percent said Trump. 

Harris had an edge when asked which candidate was better for preserving democracy. 

She had a tiny lead when Americans in the three states were asked which candidate would better handle a crisis. 

In Pennsylvania, 49 percent said Harris and 47 percent said Trump. 

In Michigan, 51 percent said Harris, 47 percent said Trump and in Wisconsin - where Harris has the smallest lead - 49 percent said Harris and 48 percent said Trump. 

Harris will return to Wisconsin to campaign on Friday, while Trump will head to Pennsylvania for a rally Monday night.
