The GOP is basically universally bad at fiscal policy. They spend big, mostly on warmongering and industry. Not developing industry, no no, siphoning government funds to the private sector, where I assume they have many friends.

They increase the deficit because they increase spending and then "cut" taxes. Often they don't effectively "cut" taxes for you and me: the tax burden for many Americans is raised, except for a select few who get tax cuts.

This was happening well before Trump, into Reagan. The only reason this works at all is because they get to say "oh we cut taxes!". But tax burden is very complicated, and nobody is analyzing that for the common voter.
