Is Grassley even smart enough to know he was snookered from the start on this?
If Ford doesn't show when the Republicans gave her an opportunity to tell her story under oath, the Democrats will look ridiculous. She wants an investigation, but refuses to testify?
Right now, it looks like Grassley called their bluff, and they're folding. And rather than leaving the GOP vulnerable to the claim "why wouldn't you at least listen to her", he'll leave the Democrats looking like they're trying to suppress the truth.
