It is a busy week for Kari Lake and for Republicans who harbor White House ambitions. Several are more than eager to share the stump with the Arizona gubernatorial candidate, a fact that Democrats believe underscores their arguments about the "ultra MAGA" right and the rise of GOP extremism.

Tuesday morning in Scottsdale, South Dakota Gov. Kristi Noem will have coffee with Lake and her supporters. The next afternoon in the Phoenix suburbs, Lake will share the stage with Texas Sen. Ted Cruz. Former President Donald Trump arrives Sunday to host a rally in the town of Prescott Valley.

Some have already stumped for Lake, such as Florida Gov. Ron DeSantis in August. Others have promised they will, like Virginia Gov. Glenn Youngkin, but haven't yet put a date on the calendar.

"Why is it a surprise that Republicans are helping Republicans?" a Noem spokesman asked RealClearPolitics before getting a plug in for the candidate: "South Dakota is proving that freedom gets results, and Kari Lake will bring the same principles to Arizona."
