Unless the immigration reform includes some form of amnesty which is all you are going to pass with this Congress, so better to wait for a better chance to get what you want. Versus trying to ram something through that no one will like.
It is time for the GOP to show that they have the stomach for a fight.
With this Democrat/RINO Senate control of this issue, they have shown that they don't have the stomach for any fight you would be happy with, so better to not do it at all.
Political reality is a bitch.
