If you’ve been thinking, “Gee, I hope there’s enough air left in the primary to justify a few more Santorum and Gingrich appearances on Sunday morning,” good news — they’re both on tap today. The highlight, though, is Biden sitting down with “Face the Nation” to explain why Mitt Romney would destroy America and why Obama’s the greatest American president of the past 500 years.

I usually don’t pay attention to the panel discussions but check out who’s set for “This Week.” Quite a clash. The full-line up via WaPo:
