O’Malley is among those appearing in enemy territory to make the counter argument to that being put forward by Republicans this week. He offered a hint of what’s likely to come on Sunday during an appearance on CNN’s “State of the Union,” when he called the GOP a “party of exclusion.”

O’Malley’s planned appearances in Tampa on Thursday night include a return visit to CNN as well as FOX radio, according to an aide. He also has meetings scheduled with a pair of national news organizations.

On Friday, O’Malley is scheduled to appear on MSNBC’s “Morning Joe,” which is broadcasting this week from a Tampa bar. Fellow guests include another Marylander — former lieutenant governor Michael Steele — and New Jersey Gov. Chris Christie (R).

As chairman of the DGA, O’Malley has often used Christie as a rhetorical punching bag, declaring once that he lives in a “make-believe world, where down is up, up is down, candy is a vegetable, and vegetables are candy.”
