Will Brownback and Tancredo Cancel Each Other Out?

Brownback and Tancredo are locked in a mortal feud over who will be the undisputed master of the second tier:

Republican presidential candidate Tom Tancredo on Monday said that an automated phone call to Iowa anti-abortion voters, paid for by Sen. Sam Brownback's campaign, that questions Tancredo's commitment to anti-abortion politics is "despicable."

"No one can attack me for my position on life - no one," Tancredo said during an appearance on Jan Mickelson's morning program on WHO Radio.

Brownback's campaign, in the phone call, questions Tancredo's financial ties to John Tanton, a physician who helped found the Northern Michigan Planned Parenthood Association, which provides women's health services that include abortion.

Tanton has donated money to Tancredo.

Tancredo said Tanton's support stems from their mutual interest in the immigration issue and has nothing to do with the Colorado congressman's stance on abortion.

"I have been pro-life since I was in the state Legislature 30 years ago," Tancredo said.

The phone call to anti-abortion voters says Tancredo should donate money received from Tanton to anti-abortion efforts in Iowa.
