Former President Bill Clinton will spend the day before the election on a four-state campaign swing.
He'll campaign for candidates in New York, Kentucky, West Virginia and Florida throughout Monday.
With observers saying Republicans gains could be higher than previously predicted, Clinton will hit a race in his adopted home state and then campaign for three Democratic Senate candidates in tight races.
In New York, Clinton will campaign with Rep. Scott Murphy (D-N.Y.) in his toss-up raced against Republican challenger Chris Gibson.
In Kentucky, he will campaign with Senate candidate Jack Conway (D) in his race against Republican Rand Paul.
In West Virginia, Clinton will hit the campaign trail with Gov. Joe Manchin (D) in his bid for Senate against Republican John Raese. Raese had brought Sarah Palin in over the weekend to campaign for him.
And, in Florida, Clinton will campaign with Rep. Kendrick Meek (D) and Democratic gubernatorial candidate Alex Sink. The Meek appearance was announced this past weekend, after reports broke Clinton asked Meek to drop out of the race and throw his support to Independent candidate Charlie Crist. Clinton and Meek both denied Clinton asked Meek to withdraw from the race. Meek is in a distant third place in the polls behind Crist and Republican candidate Marco Rubio.
Republicans need a net gain of 39 seats to re-take the House of Representatives and 10 seats to re-take the Senate.
President Obama, who spent the weekend on a four-state swing for get-out-the-vote rallies, has no public events scheduled for Monday.
