Michele Bachmann could be in big trouble in 2014.

A new Public Policy Polling survey finds businessman Jim Graves, the likely Democratic nominee for Bachmann's House seat, leading the Tea Party congresswoman by a 47 to 45 percent margin. Graves' narrow advantage, which is well within the poll's margin of error, is a huge red flag for Bachmann considering the strong Republican lean of Minnesota's 6th congressional district. Find out why the poll is just the start of the bad news for Bachmann.
