Why are the Senate Republicans putting their political lives on the line for a president so ready to betray them? I don’t know. Perhaps the Republicans don’t either. For their own sake, they’d better figure it out. The drip-drip-drip of bad news will continue through Election Day. It’s shrewd to fear a party leader threatening to put your head on a pike. At what point, however, does avoiding such a fate end up causing it?
