Collins is walking a fine line. the left (democrats have been threatening her. if she does decide to oppose kav, it sends a signal that she can be successfully threatened, which means that the threats will come more and more whenever a close controversial vote nears. her only hope is to confirm kav, to let the left know that she cannot be cowed.
There will be more over the weekend????
Otherwise the democrats are toast..
This may turn out to be one hell of an election booster for the GOP
But he has to be confirmed
