Review of Santorum's ineligibilty for Indiana primary ballot under way

INDIANAPOLIS (WISH) - Rick Santorum won caucuses in three states Tuesday night. Nevertheless, he may have no opportunity to win the Indiana GOP primary.

At the Marion County voter registration office, it's been determined that the Santorum campaign is 24 signatures short of the requirement to make the Indiana ballot. A review is under way.

"We're not trying to keep anyone off the ballot," said Cindy Mowery of the voter registration office, "and we want to do everything we can to help the candidates."

But it's likely Santorum will be ruled ineligible, and his campaign is already considering legal action.

"I anticipate that the Santorum campaign will aggressively pursue all of its options to ensure that Rick Santorum is on the Indiana ballot," said state Sen. Mike Delph, a Santorum volunteer.

The problem can be attributed in part to new congressional district lines, but the Santorum problem is also something the folks in the voter registration office don't expect.

"Not at the national level," Mowery said.

Santorum could still run a write-in campaign in Indiana.
