The RATs will give her 45 votes.
Their support for her is a no-brainer.
First, it splits the majority.
Second, there is an abundance of evidence that Harriet is Sandy Baby without the background - that she can and will be rolled by the leftists on the court.
Third, the fact that she will (probably) be seen as a failure will blacken the name of W long after he's back in Texas.
It's a trifecta for the Dems, and their support is all but assured.
There are at least five (actually, many more) leftist Republicans who will go along.
You can swear her in - unless SHE withdraws, and I don't know why she would.
