The balance of power in the U.S. Senate hinges on several key races around the country.
One that could dramatically alter the landscape is Florida's race between Rep.
Val Demings (D) and Senator Marco Rubio (R).
Senator Rubio is looking for a third straight general election win after taking over the Senate seat from George LeMieux in 2010.
Rubio has the wind at his back heading into the election, with Demings looking to pull off a major upset.
