Clinton and Trump chase last-minute support

As the presidential candidates squeezed in campaign visits to battleground states Monday just hours before voters go the polls on Election Day, Hillary Clinton's campaign touted its ground game while Donald Trump's portrayed him as the candidate of change championed by enthusiastic voters.

The return to the campaigns' core strengths and longtime arguments came as polling continued to slightly favor Democrat Clinton but gave her party only an even chance of also wresting control of the U.S. Senate away from Republicans.

'We're really focused on turning out our supporters,” Clinton's campaign manager, Robby Mook, said on NBC as the campaign announced it had made 8.1 million phone calls and knocked on 6.2 million doors over the weekend. 'We're seeing historic turnout.”

Trump campaign manager Kellyanne Conway on MSNBC cited supporters in Minnesota who had walked miles to a Trump event there Sunday as an illustration of the commitment of voters who would help solidify the upper Midwest for the GOP nominee.

'We obviously have had Team Clinton on the run in terms of where they're going to schedule and deploy their super surrogates in the final days,” Conway said, predicting Trump would win Michigan despite the Clinton deployments.

Clinton, 69, and President Barack Obama were scheduled to visit Michigan, as were Trump and his running mate, Mike Pence. Clinton held a 4.7 point lead in the state's RealClearPolitics polling average with third-party candidates included. Obama won the state's 16 Electoral College votes by wide margins in both his elections.

Trump, 70, would appeal to voters there and in Rust Belt states such as Pennsylvania because of his populist message, particularly on trade, Conway said.

'He talks about the rigged corrupt system not working for the common man,” she said.

Mook said Clinton's campaign was focusing on states that have little or no early voting, but polls have showed a tightening race since late October when Clinton led by more than 11 points.

Clinton was also scheduled to campaign in Pennsylvania including a star-studded Philadelphia rally with the president, first lady Michelle Obama, former President Bill Clinton, daughter Chelsea Clinton and singers Bruce Springsteen and Jon Bon Jovi and then to finish the night at a North Carolina rally with her family.

Trump was continuing a grueling pace and was scheduled to appear in Florida, North Carolina, Pennsylvania, New Hampshire and Michigan. Other Trump surrogates expected on the trail included 2008 vice presidential nominee Sarah Palin, former rivals Ben Carson and Rick Santorum - who appeared in Marion - and former Rep. Michele Bachmann.

Several polls Monday gave Clinton an edge nationally, including a Bloomberg Politics survey that had Clinton ahead by 3 points. She had 4-point leads in the NBC News/Wall Street Journal poll, the ABC News/Washington Post tracking poll and the CBS News poll.

Only the CBS and Bloomberg surveys contacted voters Sunday, meaning few polls are likely to reflect the full effect of Sunday's news that - after reviewing recently discovered emails - FBI Director James Comey was sticking to his conclusion that Clinton's private email use as secretary of state didn't warrant criminal prosecution.

Nate Silver's widely watched FiveThirtyEight forecast a 66 percent chance Clinton would win the election.

The New York Times model gave her a better chance, 84 percent.

And a Reuters/Ipsos States of the Nation survey gave Clinton even better odds - a 90 percent chance of defeating Trump, forecasting she was on track to win 303 Electoral College votes out of 270 needed, to Trump's 235.

Democrats' outlook for retaking control of the U.S. Senate was dimmer. FiveThirtyEight put the chances at 50 percent.

For the U.S. House, the Cook Political Report projected Democratic gains of five to 20 seats, short of those needed to dislodge Speaker Paul Ryan's GOP majority.
