There might be five GOP Senators on the side of the citizens.
Sessions, Cruz, Lee, Vitter maybe Grassley.
Nowhere near a majority.
85% of GOP voters and 65-70% of the citizens want the laws enforced and the border secured. It could be THE winning issue if the GOP wasn’t opposing the citizens on it.
Only a few are speaking out, but I believe a good majority of GOP senators do oppose amnesty, but that's not much in the senate since every Dim supports it.
