TAMPA, Florida – If you’ve been watching the Republican National Convention at home, you probably missed the speech former Representative Artur Davis of Alabama gave on Tuesday night. Sandwiched between Ted Cruz, the Tea Party darling who won an impressive come-from-behind victory in Texas’s GOP Senate primary, and Nikki Haley, the strikingly youthful Indian-American governor of South Carolina, Davis was overshadowed in most of the media coverage. MSNBC decided not to air Davis’s speech at all, which was a noteworthy omission given that Davis had cut his political teeth as a Democrat and indeed as an enthusiastic early backer of President Obama.
