The thing there is the GOP was financially conservative a few decades ago and it's like nobody bothered to update the wiki.

They'll ride it forever. My dad still insists "Protecting the environment is conservative, look at the EPA made by Nixon" as if there hasn't been clear and deliberate anti-environmental policy since then.

After 30 years of empirical reality demonstrating that if you want a government that is responsible with money, you must vote democrat, Donald Trump was still voted in because "He's good for the economy"

He is not.

Late response but I can't leave the assertion that voting Democrat results in fiscal responsibility unchallenged. Their experiment with neoliberal economics and aggressive disinterest in pursuing anti-trust and anti-monopolistic policy have bankrupted most of rural America. At this point if fiscal responsibility is a goal you'd pretty much have to vote 3rd party or independent (for as much good as that does anyone).
