Governing rates NH gubernatorial race a ‘tossup’

In the latest update to its 2012 gubernatorial projections, Governing has changed its rating for the New Hampshire race from lean Republican to tossup.

We’re shifting this race from lean Republican to tossup — not because of any significant partisan movement, but rather because New Hampshire’s race is the least well-formed of any on this list. … Despite some historical difficulties in the state, Obama has chalked up a series of modest leads over New Hampshire resident Romney in recent polls. In addition, some voters may appreciate the idea of a Democratic brake on a GOP-dominated Legislature. But the tenor of the race is likely to remain a question mark until at least the September primary.

The ratings are based on interviews with state and national analysts and are updated throughout the campaign.
