Don't make me laugh.
There's every indication that Republicans are too shallow to realize that, whatever party is in power, the left control the mechanism of government, education, and the law, and that means they control the economy.
A Republican might sit in the White House, but reds will be sitting in all the other important chairs.
Actually, with the right constitutional conservative President (e.g., Ted Cruz) in power and leading a Republican Congress, much of the standing federal institutions and bureaucracies could be eliminated.
The Education Department could be abolished with education responsibilities left to the state where they belong.
Laws could be passed declaring that CO2 is NOT a pollutant and laws could be passed removing ANY responsibilities to manage waterways’ pollution from EPA management (e.g., move all that responsibility to the Army Corps of Engineers). Those are just several things (there are MANY others) that can be done to rein in the EPA’s jihad against the American economy and the American people & businesses. Funding for EPA staffing could also be vastly reduced so that they would have to RIF 90% of their sitting bureaucratic overlords. EPA could have its staffing payroll also vastly reduced by only allowing a SPECIFIED certain number of employees at each pay level. They would have to have massive down gradings with senior folks bumping more junior folks at lower levels. This couldn’t happen to folks more deserving of this treatment. Let most of them go out into the economy they have been trying to destroy and compete with the rest of us. Most of those that remain would have to do with lower pay and lower expectations of promotion possibilities.
True tax reforms/simplification could be undertaken followed by MASSIVE reduction in IRS staffing levels.
Much of the land that the Bureau of Land Management “manages” could be transferred to the state in which the land sits. The individual sovereign states and their citizens should be responsible for their lands.
