(This can't be good news for the GOP nominee, but should be somewhat good news I would think for the Democratic nominee Mark Dayton).
Former Republican Gov. Arne Carlson announced this morning that he's backing Tom Horner's campaign for governor. Horner, of the Independence Party, will travel the state with Carlson today. Here's the release:
Governor Carlson endorses, travels state with Horner
