Romanoff within six of Bennet

Sen. Michael Bennet (D-Colo.) appears to have a real primary on his hands.

Public Policy Polling (D) is out with a poll showing former state House Speaker Andrew Romanoff within six points of Bennet, trailing 40-34.

Romanoff is also looking for a bump in the state's precinct caucuses, which begin Tuesday. A solid poll like this could be what he needs to prove to people that he has a chance, amidst some less-than-stellar fundraising.

On the GOP side, things are more wide open. Former Lt. Gov. Jane Norton leads Weld County District Attorney Ken Buck 34-17, while 7 percent go for former state Sen. Tom Wiens.
