Republicans are liars. They cannot be trusted. It is in their DNA.
They are anti-government. The only government program they truly support is defense spending. They want everyone to fight to the death and defend whatever they are able to accumulate in our political system. They seldom support any social programs that help people. They do not care very much for "promoting the general welfare" or "insuring domestic tranquility" or "establishing justice". They want tax cuts. They want their greed satisfied.
For decades, almost a century, they have pretended to support programs like Social Security and Medicaid because it was necessary for their political survival. They never really supported any of these programs. But years of lying about it, even to themselves, has imprinted in their DNA. It comes natural to them.
Now they have arrived at the point they always dreamed about but were never sure it was possible. They have persuaded enough people in this country to believe their lies and they wrap themselves in the American flag to prove how patriotic they are. They are now in control and we see their true nature.
They do not care about justice. They do not care about programs for the people. They have finally gotten all their wishes and they just want to flaunt it in front of the world.
