A slew of May primary battles begin Tuesday as the Republican establishment looks to reassert their control over a divided GOP in a number of states.

Its first big test comes in North Carolina, where business-friendly GOP groups have gone all-in for House Speaker Thom Tillis as he seeks to avoid a primary runoff and turn his focus to Sen. Kay HaganKay HaganLinking repatriation to job creation Former Sen. Kay Hagan in ICU after being rushed to hospital GOP senator floats retiring over gridlock MORE (D-N.C.). The race is a top priority for the GOP as they seek to win back the Senate.

A win on Tuesday allows Tillis to conserve resources for the general election and train his fire on Hagan, who has had a narrow lead against Tillis in most recent public polls. But if he falls short he’ll have to slog it out for another few months, potentially hurting his chances in the general election and giving the Tea Party another shot.

In the eastern end of the state, establishment Republicans face a tough challenge in defeating Rep. Walter Jones, an iconoclastic Republican who’s been a regular thorn in the side of GOP leaders. He’s facing Taylor Griffin, a former Treasury official during George W. Bush’s administration who has backing from many establishment Republicans. Griffin has also been endorsed by former Alaska Gov. Sarah Palin (R), who he worked for while on Sen. John McCainJohn Sidney McCainSenate's defense authorization would set cyber doctrine Senate Dems hold floor talk-a-thon against latest ObamaCare repeal bill Overnight Defense: Senate passes 0B defense bill | 3,000 US troops heading to Afghanistan | Two more Navy officials fired over ship collisions MORE’s (R-Ariz.) presidential campaign.
