Most despicable personal attack during an election

What is the most over-the-line, below-the-belt stunt a politician has pulled against their opponent?

I'd consider it a toss-up between George W. Bush telling racist South Carolina voters that John McCain's adopted Indian daughter was a mulatto love-child (2000), and Saxby Chambliss implying that Max Cleland, a decorated double amputee Vietnam vet, was basically a Muslim terrorist sleeper agent (2002).

Metzenbaum's claim that John Glenn never had a real job probably ranks pretty high.

A lot of politicians have gone that route, usually when the target is a career politician/government employee.

In 2010, Bill White sounded almost Romney-esque when he said Rick Perry had never had a real job and that his lack of private sector experience disqualified him from public office (which already sounds illogical on its face, but was made worse by the fact that Perry's non-government jobs were in the unimpeachable fields of military service and working on the family farm).

Right on cue for this thread, we get a pretty nasty ad from Wendy Davis.

I don't see what's so wrong with pointing out that Greg Abbott has a virulently anti-plaintiff, anti-victim record from his SCTX days and if he'd been injured today in Texas, he wouldn't have been able to get the generous payout he did. If that's not hypocrisy, what is?
