Rubio and Kasich are the best they have. Problem is will conservatives vote for a Cuban that is for amnesty?
Amnesty is not what Rubio is proposing though it may look a bit like it superficially. It's a historic problem and the solution is to vet the illegals properly. The real deals get to become citizens after stringent check and balances. The scum get short shifted back to where they came from. Here we even send them offshore for processing; Cuba sounds nice!!

But the problem hasn't been approached in years. No easy fixes, unfortunately.
EDIT: Another part of the method here is settling illegals in a THIRD country. Canada sounds about right.
