There’s a new poll from the Castleton State College opinionwerx, and it’s chock-full of good news for Governor Shumlin and bad news for challenger Randy Brock.

Topline:

The poll has Shumlin winning 60 percent of the vote. The Republican Randy Brock would get 27 percent of the vote….More than 10 percent were undecided how they would vote in the general election.

That’s a huge advantage for Shumlin. Not only is he riding comfortably above 50%, but the undecideds are astoundingly small for such an early stage in the race. Not only does Brock have to win over all the undecided voters; he has to convince a healthy number of Shumlin backers to switch sides. And he’s not gonna do that with his cookie-cutter, consultant-driven Spampaign.

(The WCAX story quoted here makes no mention of Martha Abbott or the Progressive Party. I do hope that Castleton’s surveys include the Progs. )

Making that job even harder is this finding:

Shumlin’s approval rating is also high. More than 65 percent approve of his job performance, 23 percent disapprove of Shumlin’s job performance in his first two years on the job, and 12 percent are not sure of the governor’s performance

Love him, hate him, or be ambivalent about him (there I am), Peter Shumlin has done a masterful job of positioning himself for re-election. Barring a huge catastrophe — and he’s already sailed through one of those, nee Irene — he’s got 2012 in the bag.

After the jump: A late add on another CSC survey result.

An e-mail correspondent reminded me that there was another question in the Castleton survey, which I frankly ignored because the Shumlin results were so stunning.

Respondents were also asked their view of the state Legislature, and the answers were very positive: 57.5% approve or strongly approve, 31.5% disapprove or strongly disapprove. 11% were “not sure.”

Those are pretty darn good numbers, and they further underline the problem facing Randy Brock — especially if he sticks with his off-the-rack Spampaign. With so many Vermonters approving of Shumlin and the Democratic Legislature, the boilerplate attacks on single-party rule are unlikely to bear fruit. The majority of voters see the Administration and the Legislature as basically doing a good job. That doesn’t leave much room for the Republicans.
