Supporters came through with more than $1 million for the Republican front-runner in what projects as a tight and crucial Arizona Senate race.

The two leading contenders for the seat wasted no time in using the announcement to attack each other's positions.

The poll is a major boost for Lake, who was up by statistically significant margins in both a two- and three-person contest.

The post came after Lake urged factions of the Arizona Republican Party to come together ahead of this fall's elections.

The election calendar for Arizona is likely to push Sen. Kyrsten Sinema to make a re-election announcement soon.

Independent Sen. Kyrsten Sinema of Arizona is coming under fire for billing taxpayers for her use of private planes.

The National Republican Senatorial Committee endorsed Arizona GOP U.S. Senate candidate Kari Lake on Tuesday.

Sinema has been a thorn in the side of the Democrats on closely fought bills and issues like doing away with the filibuster in the Senate.

Lake currently holds a 6-point lead over Democratic Rep. Ruben Gallego and a 25-point lead over incumbent Sen. Kyrsten Sinema.

"Arizonans deserve to have an honest broker serving them in the Senate, not another shady D.C. politician."
