You’d think similarly about Joseph Cao in LA-2. He won the special election for William Jefferson’s (of freezer cash fame) old seat. It’s a district that went about 75% for Obama. But current polls show Cao comfortably ahead of any Dem. primary candidate. Incumbency does has its perks and Cao is in a high profile situation because of the oil spill so he’s in the local press a lot.
Cao’s district is shown as leaning Dem in this survey, I believe, so he can’t be too comfortable.
