Massachusetts Republican gubernatorial candidate Charles Baker has selected state Senate Minority Leader Richard Tisei as his running mate in the 2010 election. As Boston Phoenix political reporter David Bernstein notes, “I think this pretty much makes this the most socially moderate Republican ticket in the history of ever. We’re well past the classic ‘Rockefeller Republicans’ here.”

This selection isn’t sitting well with everybody. Tisei certainly seems qualified and competent–far more competent than some past candidates for lieutenant governor, to be sure. However, one wonders if the controversy (such as it is) over Tisei’s personal life will be an issue in this campaign.

I will say this: Tisei on his worst day will likely be better than Tim Murray on his best day.
