A Catholic VP?

Could happen.

Take a look at the shortlists of the two candidates. Senator McCain's shortlist includes three Catholics:
Louisana Governor Bobby Jindal, former New York City Mayor Rudy Giuliani, and former Pennsylvania Governor Tom
Ridge. Senator Obama's shortlist includes six Catholics: Virginia Governor Tim Kaine, Kansas Governor Kathleen
Sebelius, Senator Jack Reed (Rhode Island), Senator Joe Biden (Delaware), Senator Chris Dodd (Conneticut, and New
Mexico Governor Bill Richardson.

I think it more likely that one of the Democrats makes the spot, but Governor Jindal would be an exciting choice.
