South Carolina Democrats chose a political unknown, 32-year-old Alvin Greene, to run against Republican Sen. Jim DeMint this fall.
Greene is an unemployed military veteran who hardly campaigned for the office, and his victory last Tuesday has raised questions about who backed his candidacy.
And it turns out that he's facing a felony charge.
Obama adviser David Axelrod says South Carolina Democrats deserve a strong, credible candidate. He says it's a big mystery how Greene won.
Axelrod appeared today on NBC's "Meet the Press."
