Because if Hillary is elected, it becomes obvious who the opponents of conservatism are. If we go with a GOPe pick we'll never know and the progressives will continue to run roughshod over the GOP.
Hillary supported almost everything Bush did right down to the Iraq war. She was the one pushing to invade Syria and Libya like McCain was.
When George W Bush (the Establishment man) was President he didn't secure the borders. He didn't appoint conservative judges to the Supreme Court... He sold out on trade deals...
Tell me...
Why would it be any different with some new GOP Establishment pick? None of their ‘chosen ones’ are talking about a wall or defending our jobs. And even if they did 'talk the talk' when they got in office they would NEVER do anything - - except for their fellow elites.
YOU know that Hostage.
If it's not Trump or Cruz we might as well have Bernie or Hillary... at least we won't have to pretend we like it when they screw us over and rape the country.
