Simple logic applies here, the people that are doing the criticizing: McCain, Rubio, McConnell, Graham, King, Ayotte, et. al. are not real Republicans. That is the issue, they are party infiltrators.
Look at politicians as Liberal / Conservative instead of Republican / Democrat. All of a sudden, the “sides of the argument” become clear.
McCain, Graham, McConnell, Boeher, Ayotte, Collins etc...are all liberals. Liberal republicans
How many Conservative Democrats are there? I mean honest to goodness conservatives in the Democrat party. Are there any? Anywhere?
The political war is not being fought between Republicans and Democrats. It’s being fought between Conservatives and Liberals.
