It isn't hypocrisy, it's pragmatism. Democrats have fought to try to reduce the roll of money in the political process. They've been thwarted, again and again, by Republicans and by arch-conservative Supreme Court justices, who know that money in politics tends to favor the GOP, so they don't want limits. So, Democrats have to play the game according to its current rules. There's nothing remotely hypocritical about that. I'm sure Republicans would love it if the Democrats would unilaterally disarm, but that would be a disservice to the American people.
The sports analogy here is simple enough. Let's say there's some feature of a sport's rules you disapprove of: the DH rule in baseball, the 3-point shot in basketball, or the 2-point conversion in football, for example. You can campaign your ass off to get that rule changed. But if you lose, and you're a coach, you aren't being hypocritical if you then use a DH, or call for a 3-point shot, or go for a 2-point conversion, when that benefits your team. It would be incredibly stupid to disarm unilaterally that way.
It's as if the right-wingers don't even understand what the term hypocrisy means.
