From the NY Times:
Mr. Addabbo said that just two years ago, a vast majority of the constituents who contacted his office opposed same-sex marriage. But this year, he said, of the 6,015 people in his district who had written to him or called his office, 4,839 wanted him to vote for it. “In the end, that is my vote,” Mr. Addabbo said.
Doesn't it sound not only implausible that there would be such a shift in the attitudes of his constituents but also asinine to base his vote on how many yay and nay phone calls he received? You're supposed to base your vote on whether or not you believe it's the right thing to do or the wrong thing to do.
