Coulter is a big Romney backer—not anti-Romney.
But she is right that if Ryan gets his way on illegal immigration (which unfortunately is Pence’s way) the 30 million illegals here currently will be legalized and make it impossible for a conservative to ever win election again.
If Ryan manages that, you can bet it won't be Trump's fault - yet so many are using even the thought of it to detract from the miracle of his Presidency.
