Both Texas Senators claim to oppose Obamacare. Both Texas Senators claim they want to defund Obamacare. When it comes to strategy though, the divide between Senator Ted Cruz and Senator John Cornyn is large. According to Politico, tactics is what this is all about.

Texas Sen. John Cornyn has heard the same allegation all year: He’s blindly following his junior Lone Star State colleague and tea party hero, Ted Cruz, to help shore up his right flank.

Cornyn is ready to put that to rest.

“I would say the recent events would probably run counter to that narrative,” Cornyn said in an interview Tuesday with a big chuckle in his whip office just steps from the Senate floor.

Indeed, over the past several weeks, Cornyn and Cruz found themselves increasingly at odds in a tense public battle over whether to use a potential government shutdown as leverage to defund Obamacare. After initially signing on to Cruz’s effort, Cornyn withdrew his support and became a leading critic of the tactic, helping quash any momentum his colleague hoped to gain on the Senate floor this week.

Cruz, who spent hours Tuesday using a floor speech to deride the health care overhaul, has attacked his GOP colleagues for cowering in the fight over Obamacare. He’s increasingly alienated from most Senate Republicans, who believe his tactics have hurt their party politically and put them in a weaker negotiating position with the White House.

But he has also made things more personal for Cornyn.

He refuses to publicly endorse Cornyn, the Senate’s No. 2 Republican, in his reelection bid, a highly unusual move for a senator from the same state and party. That has infuriated Cornyn allies who see it as a slight that will come back to haunt Cruz should he run for president in 2016 or need Cornyn’s help in the future.

What’s more irritating to Cornyn allies is that behind the scenes, Cruz has quietly tried to help his senior colleague even though he won’t publicly commit to endorsing him. Cruz’s political action committee donated $2,500 to Cornyn’s reelection effort, and the freshman even attended a fundraiser for his colleague last weekend in South Texas where the two men went dove hunting with big donors.

When it comes to the battle over funding Obamacare, who do you agree with? Cornyn or Cruz?
