It's not that the Bushies are fake republicans it is that their agenda is different than both the republicans and socialists.
When you run for President you have to have a "D" or an "R" behind your name on the ballot to be elected.
The socialists went for the "D" and the Bushies went for the "R" ,One difference is the socialists have the democrat party from top to bottom and the Bushies have the top part of the republican party with a lot of confused republicans below them.
Bush's Immigration policy is a reason not to vote for him but there is never a reason to vote for the socialists (Dems).
