The Scott Brown who may rescue the country from Obamacare is not a talk radio conservative.
Strong on defense and school choice, opposed to the Obama administration’s signature initiatives, Brown voted in favor of Mitt Romney’s health plan in Massachusetts. He describes himself as pro-choice (subject to reasonable limitations), accepts gay marriage in Massachusetts as a settled fact, and told the Boston Herald editorial board he would have voted to confirm Sonia Sotomayor. He calls himself “fiscally conservative and socially conscious.” He’s got an environmental record too: In the state senate he voted in favor of a regional initiative to curb greenhouse gas initiatives.
Most important: Unlike his arrogant, brittle opponent, Brown has shown himself an open and accessible candidate, optimistic and without rancor. In short – he’s running exactly the kind of campaign that we alleged RINOs have been urging on the GOP for months now.
It would be a travesty if Brown’s victory is seized upon as a victory for anger, paranoia, and ideological extremism.

That would indeed be a travesty. Here’s something else that Scott Brown’s success so far makes worth a rethink. The vast majority of “talk-radio conservatives” are strongly supporting Brown. Perhaps the caricature of them as unrealistic purists willing to wreck their party is a trifle overdrawn? Maybe anger, paranoia, and extremism do not offer an adequate account of their political decisions.
