Liz Cheney, the just-announced primary opponent of Sen. Mike Enzi (R-Wyo.), says the senator was probably "confused" when he said Cheney had told him she wouldn't run against him.

She suggested Enzi may have thought she was another younger female politician in the state, Rep. Cynthia Lummis (R-Wyo.).

"I think Sen. Enzi may be confused. I think he may have me mixed up with Cynthia Lummis," Cheney said at a press conference Wednesday.

Enzi said shortly after Cheney launched her campaign that she had told him she wouldn't run against him and that he "thought we were friends."

“Well, she said that if I ran she wasn’t going to run, but obviously that wasn’t correct," Enzi said Tuesday.

Cheney said she called Enzi to tell him she was thinking about running and that she always believed it didn't matter who the other candidates would be.

"It's not true; I did not tell Sen. Enzi I would not run if he did," Cheney said. "I suppose he's just confused."

Cheney, 46 and the daughter of former vice president Dick Cheney, has made some subtle allusions to the age difference in the race, saying its time for a new generation of leaders.

Enzi, 69, said in an interview Wednesday that he's "not too old" and that he's actually "the median age" in the Senate. (Technically, that's not true; Enzi is the 25th oldest out of 100 senators.)
