O'Rourke is not Mexican. He's Irish and culturally appropriate a Mexican sounding nickname.
His father gave him that name on the day he was born, so he didn't all of a sudden choose it. There are photos of him as a baby with a shirt that had that name on it.
That doesn't transform a 4th Generation Irish guy into a Mexican.
Just sayin'.
Please show me where he ever tried to say he was Mexican. He was raised in a border town and speaks fluent Spanish, but he's never claimed to be Mexican. Ted Cruz...a.k.a.......Rafael Edward Cruz IS of Latino heritage but he is trying to pass himself off as a white anglo but that's okay since he's a Republican, huh? Oh, and he was born in CANADA whereas Beto was born in TEXAS!!
