I've seen Sen. Cruz quoted as saying he can only speak what he describes as "Spanglish".
You can look around at the leftist news reports to see claims that he has refused to debate in Spanish "because he doesn't speak it at all".
Seems to me it could make a great difference and I keep hoping he would start immersion lessons right away.
I thought Cruz could speak it fairly well,,,,Oh well we know Rubio can but so can Jeb Bush unfortunately!
