Nope. We don't. We just give in, time and time again, rather than simply get what needs to be done done.
I doubt that Allen has the votes, I'm pretty sure that his advisers know this, and if we had leadership, they'd be on the phone making a deal right now. Horse trading - we'll stop contesting lost causes if they allow up/down votes on nominations or some other concession. Instead, we'll wait, Allen will go away in a whimper, and we get nothing.
As for demands to share power - eh. What of it? Soreloserman tactics. It was our job to win, we lost, let them have a crack at it, and somewhere along the line, figure out how to actually get Bush to use his veto.
There may be a deal to downplay the FBI investigation of those phony phone calls in return for Allen going away.
