While Republicans are conducting their convention business in the Twin Cities, they may want to take a moment and attempt to woo a few more Minnesota voters on John McCain’s behalf. A new Time/CNN poll of Minnesota has Democratic nominee Barack Obama with a 12-point lead among Minnesota voters in a head-to-head match-up 53 percent to 41 percent. When third-party candidates Ralph Nader, Rep. Cynthia McKinney and Sen. Bob Barr are added to the mix, Obama’s lead increases to 14 points over McCain.

Obama previously held a 10-point lead. The poll surveyed 742 registered voters in Minnesota and has a 3.5 percent margin of error.
