Let's put it this way: If the Democrats controlled Congress and the White House, this bill would have looked very different. If Senate Republicans had filibustered, Senate Dems would have invoked reconciliation to end the filibuster and would have passed whatever they wanted. The bill would have included Obamacare subsidies, a cut in DHS funding (especially ICE funding), some kind of amnesty for DACA kids, no money for charter schools, a much smaller increase for defense spending (if not a decrease), etc., etc. And President Hillary Clinton would have gladly signed the bill. So perhaps we should be grateful for what we obtained and work to get more Republicans elected to the Senate.
What difference would it make? We will still end up with the same thing.
The "same thing"? We have 8 years' worth of huge personal income tax cuts, most of which even a Dem-controlled Congress will likely extend. We have dozens of new solid conservative judges on the federal judiciary and a great conservative added to the Supreme Court. Those are long-term positives. We have at least four years of deregulation and overseas-parked American money pouring back into the U.S. And, thanks to Trump's efforts, we are now starting to rebuild our military.
I'll tell you one thing that is turning many centrists and center-rightists against the GOP: the party's refusal to support reasonable, common-sense gun control measures like universal background checks and raising the age for rifle sales to 21. We have much more thorough controls on owning and buying cars, but no one would rationally say that our right to own and use a car has been infringed.
Another thing that is turning off many centrists and center-right folks to the GOP is the party's refusal to make reasonable compromises on immigration reform.
