President Obama will spend most of Election Day in closed-door meetings, but he will conduct radio interviews with stations based in states with competitive Senate races.

Obama is scheduled to do interviews with radio stations in Los Angeles, Chicago, Jacksonville, Fla., and Las Vegas.

Sen. Barbara Boxer (D-Calif.) faces a tough reelection challenge in her state, and Obama has a vested interest in the Democrat winning his old Senate seat in Illinois.

In Florida, Rep. Kendrick Meek's (D) Senate campaign got a shot in the arm after reports surfaced that former President Clinton asked him to drop out and support Independent candidate Charlie Crist. Clinton and Meek denied those reports, and the White House has not commented on reports that administration aides were involved in the negotiations.

And Senate Majority Leader Harry Reid (D-Nev.) is in a tough fight with Tea Party candidate Sharron Angle (R). First lady Michelle Obama was on the stump with him Monday, and Obama has campaigned for the leader several times.

The president also will likely try to boost House candidates in these states, but predictions and polls have the GOP winning back the lower chamber.

Obama also did radio interviews on Monday in an attempt to get out the vote.
