Interesting If True

In "Hispanics must recall the reason their parents came to America in the first place", Silvio Canto notes:

Here is a message to the GOP:  Amnesty or immigration reform had nothing to do with Obama carrying Hispanos by a huge margin... 

Why do I say that immigration reform had nothing to do with Obama's reelection?  

First, he never lifted a finger to do a thing about immigration reform. In fact, no immigration reform law has ever been passed by a Democratic president or Congress. They talk a good game but they never score! 

Emphasis mine.

Is this true?

I'll have to do some looking.  The History of U.S. Immigration Laws seems like a good place to start.
