For a while, potty-mouthed Rep. Alan Grayson of Florida has seemed like one of this cycle’s most vulnerable House Democrats. He represents a district that is usually pretty Republican (Obama carried the district by 5 percentage points) and that Republican Bill McCollum represented for a lot of years. Grayson’s style in office has been the opposite of a centrist, carving out his niche as the sneering and obnoxious id of House Democrats. Yet the GOP had trouble finding a top-tier challenger, someone who has run a race or two before and who has a good reputation in that section of Florida.

Now they’ve found one: Florida state representative Kurt Kelly, who’s making it official today.
