That's what Democratic Congressional District 9 challenger Bill Mitchell suggests, touting an internal poll showing Republican Bilirakis with 45 percent support and Mitchell with 25 percent. Not exactly a horse race on the surface, but the Mitchell folks argue it's a sign of Bilirakis' weakness.

"This is a clear sign of Bilirakis’ vulnerability, as on Election Day most undecideds typically vote for the challenger," pollster Margie Omero of Momentum Analysis writes in a memo. "In fact, these undecided voters lean Democratic. They are more likely to self-identify as Democrats (46 percent) than as Republicans (37 percent). And they are more likely to vote for the Democratic candidate in the generic ballot question (42 percent Democrat, 34 percent Republican, 24 percent undecided/other)."
