Sources tracking the air war tell POLITICO that the floundering candidate has reserved $31,540 for broadcast and $7,092 for cable ads to run from next Monday through Sunday.

This comes on the heels of a $55,838 buy over the last nine days for Cheney’s first ad, which aimed to rebut the attack that she’s a carpetbagger by highlighting her deep roots in the state.

It is not immediately clear if the new expenditure will pay to run a shorter version of that same spot or if she will roll out a new commercial in the wake of the explosive back-and-forth between the candidate and her sister over gay rights.

The previous ad was 60 seconds. Reservation records show that the broadcast buy this time is for a 30-second spot, but the Fox News buy is for 60-second chunks.

Two Cheney campaign officials did not immediately respond to requests for comment.

More than half the money is going into the Casper market, with $11,000 in Cheyenne. The rest is spread across peripheral markets.

Cheney, challenging Sen. Mike Enzi in next August’s primary, said on Fox News Sunday that she opposes gay marriage. That prompted her sister, Mary, and her wife, Heather Poe, to criticize Liz Cheney on Facebook.

Dick and Lynne Cheney then issued a public statement that, essentially, sided with Liz. Mary Cheney told POLITICO Magazine that she is not supporting her sister’s bid.
