The main attraction in Public Policy Polling's look at Vermont was probably the Senate race (where Bernie Sanders is far ahead of any opposition), but they also threw in the Governor's race. You might be asking "Didn't we just do this?" but Vermont is one of only two states left where there's a gubernatorial race every two (instead of four) years, so we already need to think about re-electing new Democratic Gov. Peter Shumlin.
Despite numbers that pale next to fellow Vermonters Sanders and Pat Leahy, Shumlin is looking pretty safe against every Vermont Republican the folks at PPP could think of. The only one who holds him to single digits, former Lt. Gov. Brian Dubie, comes within 8, but that's a positive development since Dubie was his opponent in 2010 and came within 2 points then. Interestingly, Dubie actually has better favorables (at 48/33) than Shumlin's approvals (45/36); similarly, most of the other less-known Republicans are also above water on their favorables. However, there's a large enough Democratic registration advantage here, and the independents (who are the largest bloc in the state) lean in a Democratic direction, that Shumlin's already polling at or over the 50% mark.
