George W. Bush can be full of surprises at times.

The former president was attending a fundraiser in Denver over the weekend to raise money for his brother, Jeb — who’s running for the 2016 Republican presidential nomination.

Then he lobbed a grenade: “I just don’t like the guy.”

“The guy” is fellow Texan — and a GOP presidential foe of Jeb Bush — Sen. Ted Cruz.

Politico reported Bush’s feelings about Cruz and noted that many in the audience were stunned by the former president’s statement. As the Texas Tribune reported:  “I was like, ‘Holy sh-t, did he just say that?’ I remember looking around and seeing that other people were also looking around surprised.”

Others have suggested that Cruz’s criticism of Jeb Bush, not to mention his criticism of the former president’s policies, has contributed to the antipathy against the fiery freshman senator from Texas.

Again, as the Tribune reports, quoting an observer who heard the comments: “He sort of looks at this like Cruz is doing it all for his own personal gain, and that’s juxtaposed against a family that’s been all about public service and doing it for the right reasons. He’s frustrated to have watched Cruz basically hijack the Republican Party of Texas and the Republican Party in Washington.”

Hijack the GOP? Gee. Do ya think? The guy storms into office, grabs the first microphone within reach and starts bellowing about how the Senate Republican caucus isn’t conservative enough, doesn’t confront Democrats enough, doesn’t do enough to push the ultra-conservative agenda that Cruz and other TEA Party favorites desire.

Welcome to the club, Mr. President.
