Gubernatorial candidate Mike Freeman appears to be maintaining his lead in the race for the DFL party endorsement. This weekend Freeman won two more DFL straw polls, at the party's 3rd and 4th Congressional District conventions -- which represent Minneapolis's southwestern suburbs and the St Paul area. About HALF the delegates polled indicated they're backing Freeman, with second-place finisher Skip Humphrey scoring about 37 percent.
