I was going to link to the piece, but then decided I didn't want my fingers to explode or my soul to be crushed, so I decided against it. This article on the Huffington Post, though, will at least point out many of the factual errors she makes. Anyone who wants to track down the original article on their own is free to, course. The best search terms are probably "Ann Coulter," "Latino," "immigration" and any insulting phrases you can think of.
I'll just say that the main thesis of the article is why should Republicans pass immigration reform when all those people are going to vote for Democrats anyway.
The answer is pretty obvious.
1) Not all of "those people" vote for Democrats.
2) More Latinos would probably vote for Republicans if they didn't keep reading articles like hers.
