Two polls released Thursday from Quinnipiac are very telling about where the presidential campaigns stand.

The first poll showed a tie in Iowa. Donald Trump previously led in every poll taken there since August. Hillary Clinton will campaign in Iowa on Friday, which suggests her advisors see some weakness there and a chance to run up the score.

The other poll surveyed North Carolina voters and showed Clinton ahead by three points. Republican Mitt Romney won the state four years ago. Clinton doesn’t have to win the state, which makes her event in North Carolina Thursday appear that much more aggressive.

She stepped on stage in Winston-Salem with the woman her campaign has called The Closer—Michelle Obama. It was their first rally together this election.

“People wonder, yes, Hillary Clinton is my friend,” Obama said.

She urged supporters to vote now.

“Hillary has done her job. Now we need to do our job and get her elected president of the United States,” Obama told the crowd.

While in Ohio, Donald Trump seized on the latest disclosures from WikiLeaks. The stolen emails have become the gift that keeps on giving to his campaign.

A newly released memo from a Bill Clinton aide claimed Clinton Foundation donors were encouraged to give to Clinton directly, too.

“If the Clintons were willing to play this fast and loose with their enterprise when they weren’t in the White House, just imagine what they’ll do if given the chance to once again control the Oval Office,” Trump said at a rally in Springfield, Ohio.

While Trump stumped for votes in Ohio, a campaign advisor told Bloomberg Businessweek their strategy also involves depressing turnout among women, minorities, and young people by using negative ads mostly online.
