"In Arizona, we will watch that carefully. We'll look at John's record and his score," Club for Growth President David McIntosh told The Hill during a Tuesday breakfast sponsored by The Christian Science Monitor.

Both Tea Party-leaning congressmen have been supported in the past by the group, which has also been critical of McCain.

"We'll see if either of the two members, you're right, they're people the Club's supported and thinks well of in Congress, does one of them decide to enter the race," McIntosh continued. "We'll do research including polling and determine, is there a path to victory and is the money well spent? And by a path to victory, some institutions only engage in things when they're 90 percent sure will lead to victory. The Club is willing to take greater risk. ... So that'll be an assessment we do in Arizona if the race materializes."

The Club has long been the biggest player on the right in GOP House and Senate primaries, and has helped elect a number of conservative Republican senators, including Marco RubioMarco Antonio RubioUS-Saudi Arabia policy needs a dose of 'realpolitik' Media cried wolf: Calling every Republican a racist lost its bite Rubio criticizes reporters, Democrat for racism accusations against McCain MORE (Fla.), Rand PaulRandal (Rand) Howard PaulUS-Saudi Arabia policy needs a dose of 'realpolitik' McConnell challenger faces tougher path after rocky launch Overnight Defense: Iran seizes British tanker in latest escalation | US, UK to discuss situation | Trump says 'no doubt' US downed Iranian drone after Tehran's denials | Pentagon's No. 2 policy official to leave | Lawmakers worry about Defense vacancies MORE (Ky.) and Ted CruzRafael (Ted) Edward CruzHow to reduce Europe's dependence on Russian energy Cruz calls for 'every penny' of El Chapo's criminal enterprise to be used for Trump's wall after sentencing Conservatives defend Chris Pratt for wearing 'Don't Tread On Me' T-shirt MORE (Texas), a trio of likely presidential contenders.

McIntosh suggested that the Club is likely to not endorse in a presidential primary, though he said the group will continue to be vocal in criticizing those whose policies don't align with the Club's. He has already slammed former Arkansas Gov. Mike Huckabee, a longtime foe of the organization.

"If history repeats itself, we won't be endorsing a candidate for president," he said. 

The group has also taken the blame for backing primary challengers who flamed out in the general election — the Club helped defeat Sen. Richard Lugar (R-Ind.) in a primary in 2012, only to have its endorsed candidate, Richard Mourdock, blow the race against now-Sen.

McIntosh said some of the other Republicans facing reelection that don't align completely with the organization aren't likely to face their wrath this time around.

When asked which senator he most wanted to defeat, he said "Harry ReidHarry Mason ReidDems open to killing filibuster in next Congress Webb: Questions for Robert Mueller Steyer's impeachment solution is dead wrong MORE." But he said, if Nevada Gov. Brian Sandoval is the GOP candidate, the Club would stay on the sidelines. The likely front-runner, if he runs, has come under fire from conservatives for tax hikes he's pushed in the state. 

"Everything I'm hearing is, if he decided to run, it'd clear the field," McIntosh said. "Because of his record of raising taxes, he'd be someone the Club would not engage in supporting and use the resources for others."
