FOOL LOUISIANA VOTERS ONCE, SHAME ON…. When Sen. David Vitter (R-La.) first ran for statewide office, he ran on a “family values” platform, and promised Louisianans he would a champion of the religious right’s agenda. Voters believed him; he was elected fairly easily; and then he got caught with prostitutes.

Six years later, Vitter’s back to making the old promises all over again. Brian Beutler flags this amusing item:

Sen. David Vitter (R-LA), along with a handful of other Louisiana politicians, has signed on to the North Central Louisiana TEA Party Patriots Candidate Pledge.

That includes a promise to “Conduct myself personally and professionally in a moral and socially appropriate manner.”

It takes an unusual amount of chutzpah to even attempt something like this. Here we have a right-wing politician running on a family-values platform … then getting caught with hookers (at least one of which was hired while Vitter was on the floor of Congress) … then running for re-election anyway … then vowing to conduct himself “personally and professionally in a moral and socially appropriate manner.”

And in case the irony weren’t quite head-shaking enough, also note that Vitter is expected to win easily.
