I would also vote for Cruz if I lived in Texas, but I do hold it against him that he ran for President while Canadian.
I don’t really even know what to make of the NBC clause anymore.
It seems like it’s not going to be enforced in any way, except of course against a Republican candidate for president, I’m guessing.
Personally, I’m not going to hold this against Cruz, because imagine if we did have to choose our president between Hillary Clinton and Ted Cruz.
I’d have no choice but to vote for him, Canadian or not.
