Because Republicans support amnesty 100%. The donors they care about want it badly. The 2014-2016 Congress exists for one reason: to make sure of amnesty. They will not accomplish anything else in two years.
And that is 100% correct and why none will get my vote, unless one of them rocks the podium and stands up and says what needs to be said and make the GD demands mentioned in 163.
For me personally, I'm not going along with it anymore.
