Back when opposition to the Iraq war started to gain steam, activists tried to pressure like-minded members of Congress to put an end to the whole thing by cutting off funding by voting against the annual Defense Authorization Act. Here’s how it would normally go:
Activists: Hey! Why are you voting for funding the war if you’re against it?
Politician: Well, even if we were to end the war we’d still need to fund a withdrawal. So it doesn’t make any sense to vote against defense funding if your goal is to stop the war.
But now Republicans blocked the same Defense Authorization Act in order to delay the repeal of Don’t Ask Don’t Tell. So when the politicians which the anti-war activists went after told us that it was political suicide to block defense spending in order to shape military policy, they were telling us a lie.
