Democratic presidential nominee Hillary Clinton leads Donald Trump in the battleground states of Pennsylvania and North Carolina, according to polling released Sunday.

{mosads}Clinton leads Trump, the Republican nominee, by 8 points in Pennsylvania, 45 percent to 37 percent, in the CBS News Battleground Tracker poll.

In North Carolina, she leads him by 4 points, 46 percent to 42 percent.

The poll also shows Clinton’s email troubles are still on the minds of voters. Almost half of voters surveyed across 13 battleground states think Clinton’s explanations regarding her use of a private email server while secretary of State are getting “less believable.”

Voters are also more likely to feel that her campaign is driven by her own desire to be president. While 77 percent say that’s her motivation, 30 percent say she has a sincere desire for a better America. Fifty percent feel the campaign is driven by doing what donors and party leaders want.

The majority of voters also feels like Clinton’s and Trump’s outreach to minority groups is based on votes instead of actual attempts to help people: Sixty-five percent say that of Trump, while 64 percent say it of Clinton. 

The poll was conducted among 3,675 registered voters in 13 battleground states. The margin of error for North Carolina is 4 percentage points and 4.1 percentage points for Pennsylvania.
