It’s not Obama’s fault that we don’t have immigration reform. That is the fault of the white supremacist Republican Party. There’s really nothing Obama could have done to pass comprehensive immigration reform.
Obama however has tremendous discretion over how to enforce immigration laws and his aggressive implementation of those laws leading to record deportation has severely depressed Latino belief in the American political system at a time when Democrats not only should be wrapping up Latino voters for the next generation but need them in the midterm elections. The decision to implement the laws in this way, I guess an attempt to show he was tough on undocumented migration to buy rhetorical points he could then use to pass legislative reform, was a huge error, both morally and politically. And it is making a difference that hurts Democrats.
