Former Vice President Dick Cheney insisted he would not play a prominent public role in daughter Liz Cheney's bid for Senate in Wyoming, but on Sunday he issued a pointed critique of those who support the man she's challenging.

Cheney attacked Sen. Mike Enzi, R-Wyo., for drawing much of his fundraising money from outside of Wyoming.

"Mike has a record, if you go back and review his finances, he gets most of his funding from Washington-based PACs," Cheney said. "He doesn't get much money from Wyoming."

Cheney also touted his daughter's strong fundraising in the third quarter, during which she brought in more than $1 million, besting Enzi's total of just less than $850,000.

The Republican primary match-up between Liz Cheney, who has never held elected office, and Enzi, a three-term senator, initially came as a surprise to many Republicans, who doubted Liz Cheney could successfully attack Enzi for not being conservative enough.

But her father's support and the strong fundraising quarter indicate the race will be a competitive one moving forward.
