In the middle of the Republican establishment’s heads exploding over the possibility of a Newt candidacy, Gingrich has been endorsed by former Congressman, and convicted felon, Randall “Duke” Cunningham:

Jailed ex-Congressman Duke Cunningham wants Newt Gingrich to know he’s got the Republican presidential candidate’s back.

Cunningham apparently has been watching the Republican presidential primary debates while spending 100 months in a Tucson, Ariz. federal prison. Cunningham, a Republican who represented northern San Diego, pleaded guilty to conspiracy and tax evasion in 2005 in one of the biggest federal bribery scandals in recent memory.

Cunningham tells Gingrich in an electronic message he says he sent to the candidate last month that his fellow prisoners, and their families, support Gingrich

Heh.
