The perils of a potential Pryor filibuster

Quin Hillyer writes that Southern (and Catholic) Democrats may face a voter revolt if they try to block judicial nominee Bill Pryor:

But if the liberal activists pull the filibuster trigger in this case, their attempt at character assassination is likely to backfire on several southern Democratic senators who will be forced to explain why they joined a patently anti-southern attack. It could also hurt Rust Belt Democrats by angering millions of Catholic voters.

I’m wondering if Bill Pryor is the nominee that breaks the filibuster logjam. Even if the Republicans fail to get a cloture vote, they could force the Democrats to use up political capital defending their obstruction of a well-qualified judicial candidate. It’s a win-win.
