Republicans dominate the Florida Senate -- so much so, that many run unopposed.
But this year, more Democrats are challenging Republicans. The reason is a little-known loophole in campaign finance law.
State senate candidates typically raise hundreds of thousands of dollars. And when they run unopposed, they can give that money to the state party to use on more competitive races.
But political consultant Peter Schorsch says Democrats have found a way to keep that money out of GOP coffers.
