Why it took so long is a mystery to many who have followed this unpopular legislative proposal for years, but Senator McCain (R-AZ) yesterday finally made his most public denunciation of EFCA since his floor speech in June 2007.  From yesterday's CNBC interview with Maria Baritiromo:

BARTIROMO: In addition to taxes, unions. Why haven't you made the union issue a campaign issue? That is, the right to have a secret ballot. Why isn't this a major issue on your agenda?

Sen. McCAIN: You know, we've talked about it a lot and unfortunately, there's three or four issues that you can get out strongly. But this is--we've been talking about for a long time. This is a threat to the fundamental of labor management relations. It's fundamental to democracy, the right to have a secret ballot. The way that Senator Obama envisions and the unions--and this is their big push, and they've gotten commitments from Senator Obama and Senator Biden--union organizer goes to your house and says, `Hey, Joe, can I sign you up for the union?' That is--we all know what that opens the door to. It's dangerous for America, it's dangerous to small business and I think it's a threat to one of the fundamentals of democracy.

BARTIROMO: Will you veto the bill?

Sen. McCAIN: In a New York minute, if I may say that. I will do everything in my power to block such legislation. And imagine, Senator Obama, Nancy Pelosi and Harry Reid pushing the union agenda. It'd be very, very, very unfortunate.

Not the most thorough, well-articulated critique of the bill, but a clear and public statement of his position.  (Too bad the Senator didn't just refer to our white paper on the issue.)
