Republican Todd Akin is hoping to change the focus of Missouri's U.S. Senate race from himself and "legitimate rape" to his Democratic opponent, Claire McCaskill, and stimulus payouts to her husband.

A new ad that Akin launched today ranks as his hardest-hitting to date and attempts to make the case that stimulus spending "made McCaskill rich."

The St. Louis Beacon reports today that the McCaskill camp is pointing to federal documents that appear to back up McCaskill's claims.

"This ad is factually incorrect and is exactly the kind of nasty, desperate campaigning that Missourians hate,” said McCaskill communications director Caitlin Legacki. “Todd Akin can't defend his own extreme record, so he's resorted to false, misleading attacks against Claire's family. Todd Akin should be ashamed."

Akin spokesman Ryan Hite defends the ad, as does the Missouri Republican Party, which has been monitoring – and attacking -- the business dealings of the senator’s husband, businessman-developer Joseph Shepard, for years.

“We believe this is a major point in the case against Sen. McCaskill’s record,’’ Hite said.

Here's the full text of the ad:

[ANNOUNCER] Ever wonder why Claire McCaskill called the stimulus bill “wildly successful?" The stimulus that didn’t create jobs and cost us billions? Well now we know. The stimulus made McCaskill rich. More than one million paid to partnerships owned by McCaskill’s family. When she gives us excuses, just remember this:

[MCCASKILL] “there was a group of us that went through the bill line by line...”

[ANNOUNCER] Claire McCaskill getting rich of us, line by line.

[AKIN] I’m Todd Akin and I approved this message.
