Failed Arizona GOP gubernatorial candidate Kari Lake believes that she is the best chance Republicans have of flipping a Senate seat in next year’s election.

“I’ve looked at the polling, to be honest, and I believe I’m the only one who can win that race,” Lake said at The Family Leadership Summit in Iowa, NBC News reported.

Lake, a prominent Trump supporter and election denier, said she will make a decision about a potential Senate run in the fall.

“We have an opportunity to pick up a very important seat so that when President Trump gets back into office, he can have people in D.C. ready to back him up with this incredible agenda,” she said.

However, some Republicans are worried that Lake’s focus on baseless claims of election fraud and her failed legal challenges in an attempt to overturn the results of the gubernatorial race could end up costing them the seat.

Arizona is a key battleground state in the fight for Senate control. Rep. Ruben Gallego (D) announced his run for the Senate seat in January. Gallego will succeed Sen. Kyrsten Sinema who was elected as a Democrat but left the party to become an Independent.

If Sinema decides to run for a second term, it sets up a three-day race for the seat.

In a three-way race Gallego receive 34%, Lake 26% and Sinema 19%. 21 percent said they were undecided, according to a poll released in February.

In a hypothetical race between Gallego and Lake, the Arizona Democrat received 43% support while Lake got 33%. 24 percent of respondents were undecided.
