With less than two weeks to go until Election Day, President Barack Obama kicked off his final campaign tour on Wednesday. It's a desperate dash through states where Democratic senators are fighting to keep their seats.

Republicans are poised to take control of the U.S. House of Representatives when voters head to the polls Nov. 2. Therefore, the president's last campaign tour is focused on the U.S. Senate, where he needs to keep a Democratic majority to help push thought his agenda during the next two years.

Over the next four days, President Obama will visit five states where Democratic candidates are in danger of losing their respective elections. Among them is California where long-time incumbent Barbara Boxer finds herself in a dead heat with Republican Carly Fiorona.

Also, just two days after Vice President Joe Biden stumped in Washington state for Sen. Patty Murray, (D), Obama will also stop there for a town hall meeting.

President Obama will also stump for gubernatorial candidates in Oregon, California and Minnesota. He isn't scheduled to return to the White House until Saturday.

Former President Bill Clinton continued his campaign marathon in Florida on Tuesday, pushing Kendrick Meek, (D), for the Senate seat. However, Republican and Tea Party favorite Marco Rubio still leads in the Sunshine State's polls.

Meek and Rubio squared off in their fourth debate televised statewide Tuesday night.

"We are on the verge of being the first generation of Americans to leave the next generation of Americans worse off," Rubio told the audience.
