Sorry, Vitter cannot blame his personal failures on Jindal.

The Advocate reported that Fields traveled on a private plane that carried Edwards and several others to Washington, D.C., on Oct. 30 for a fundraiser at the home of political consultant James Carville.
I’ve got news for you: LA has a laissez-faire attitude on peccadilloes (so long as they’re not dead girl/live boy sort as Fast Eddie Edwards pointed out), so Vitter’s long-ago past indiscretion (already well known when he ran for Senator) had minimal impact. The state voted twice for Clinton despite his behavior.
When the incumbent party Governor has high disapprovals (Jindals were over 60% negative), that spreads to the same-party nominee. In almost every instance when that occurs, the incumbent party loses.
Had Jindal high approvals, Vitter would have handily won. Also keep in mind the RINO Establishment hates Vitter and tried to sandbag him from two directions, and add to that that of the two RINOs, Dardenne endorsed Edwards and Angelle gave the OK for his supporters and $$ people to back Edwards. This was a world-class RINO screw-over.
