Dan Winslow and Gabriel Gomez at least seemed interesting in tonight’s Republican Senate debate, sponsored by WBZ and the Boston Globe. But Michael Sullivan, who’s way ahead in some polls, came across as old and cranky, a garden-variety right-winger who couldn’t even bring himself to support the gun-control compromise announced in Washington today.

It seems to me that either Winslow or Gomez could at least make the Democratic nominee — Steve Lynch or, more likely, Ed Markey — break a sweat. If either of them gets a chance, that is.

And, oh, the Massachusetts Republican Party has come to this: both Sullivan and Gomez attacked Winslow for being part of a governor’s team that raised taxes and passed Romneycare. If Willard Mitt Romney is now too liberal for Republican primary voters, then their candidate is headed off an electoral cliff.
