Nope. They instituted serious anti-immigrant laws here in Florida that severely hurt many businesses. For example, enormous construction projects just stopped. Just Google, "Florida immigrant law halts construction" and you'll get all sort of fantastic examples.
So yes: Right wingers did shoot themselves in the foot in order to hurt immigrants (which is what their base truly wants in their heart of hearts). The Republican legislature knew it would be horrible for the economy. They knew it was going to hurt innocent people and loads of small businesses.
They didn't care. That's what the Republican party is all about, after all: Not caring. They will actively seek to hurt their perceived enemies no matter what! Consequences be damned!

He's still planning on making everyone's teeth rot though.
