Couldn't it just be that she thinks the operation should be cancelled but that if it isn't she wants it to be funded?
Bingo
Look, I would have voted to give authorization and voted against limiting funding. I think this is known by now that I'm unfortunately in the minority in my party. That being said, BRTD was blatantly disingenuous to score political points. Look at the order of the roll call. Naturally, people opposed to the mission will first vote against giving authorization. If authorization is granted, however, that can and should sway people to vote against limiting funding because the operation is happening regardless. That's what Bachmann did. It isn't hypocritical.
Actually, a correction on my part: I was briefly under the impression that the House rejected
both resolutions. Since the resolution against authorization
did pass, the vote against defunding the operation makes far less sense. The only possible justification I could see is if Bachmann and others voted against authorization as simply a protest vote, believing that the operation was going to continue anyway (since the President claims that he doesn't have to consult Congress on this to begin with) but didn't want to defund the operation because of the reality of the matter.
