Clinton Leads in Battleground Polls - Ohio, Pa., Wisc.

 Hillary Clinton is leading Donald Trump in the battleground states of Ohio, Pennsylvania and Wisconsin, a new tracker poll showed Sunday.

The CBS News also found a leaked 2005 video of Trump's sexually aggressive comments about women hasn't weakened the backing of his supporters.

Here's the poll's breakdown of the presidential candidates' support by state:

Ohio

• Clinton: 46 percent
• Trump: 42 percent

Pennsylvania

• Clinton: 48 percent
• Trump: 40 percent

Wisconsin

• Clinton: 43 percent
• Trump: 39 percent

The poll's margin of error for Pennsylvania is 4.2 percent, for Ohio, 3.9 percent, and for Wisconsin,4.3 percent.

That poll was conducted prior to the emergence of the 11-year-old videotape, and CBS News reported it recontacted 789 of the respondents in Ohio and Pennsylvania.

For Trump’s supporters, 91 percent of his backers in Ohio and 90 percent in Pennsylvania said the controversial tape doesn't change their view of him.

Overall, 54 percent in Ohio and 51 percent in Pennsylvania said the tape didn't change their view of the GOP nominee; 44 percent in Ohio and 47 percent in Pennsylvania said it made them think worse of Trump, though CBS News reported most in the latter groups weren't supporting Trump beforehand.

In Pennsylvania, 53 percent of women are more likely than men to say the revelation makes their view of Trump worse; 42 percent of women disagreed.

In the results from recontact, the margin of error is 4 percent in Ohio and 4.2 percent in Pennsylvania.
