"there are a lot of politicians that are in mortal fear that this issue, illegal immigration,will go away. It is the source of their support and funding."
There are a lot politicians in mortal fear their money will dry up if they don't get Amnesty+ through.

And promises of presidential runs too, like Hagel and Pence in 2008.
