Josh Marshall's take on yesterday's results:
I think the big story here is Nevada. Harry Reid is weak. And Sue Lowden looked like a serviceable establishment GOP candidate who could take him out. But she self-destructed and the win looks like it will go to Sharron Angle, a hard-right Tea Partier who makes Rand Paul look like a bit of a trimmer. And no, that's not hyperbole.
This is the kind of result national Republicans have been desperately hoping to avoid. And it's the price of the 'energy' Republicans have been benefiting from on the right. In Nevada, you might say, their chickens are coming home to roost.
