On Sunday Priebus called Vice President Joe Biden "a gifted orator," while former House Speaker Newt Gingrich, R-Ga., who challenged Romney in the GOP primary, suggested Paul Ryan would hold back on any hostility out of respect for Biden's status as a senior statesman.
Priebus spoke on CNN's "State of the Union." Axelrod spoke on CBS' "Face the Nation" and Gingrich on NBC's "Meet the Press."
