Lieberman's made his choices, presumably, on principle.

There is nothing petty about principle.

So, on the very same principle, he ought to embrace the consequences of his choices.

And really, wouldn't it be in his own long-term best interests for him to do that? He could continue to act and vote on his principles, siding with Republicans or Democrats as his conscience dictates. He could prove himself a man of principle.

Unless he's just a phony.
