It is time to leave the Republican Party. There hasn’t been a fiscally conservative Republican since Warren Harding. There are few fiscal conservatives in the House and none in the Senate.
Many people think that fiscal conservatism is cutting taxes. This is partially true. A fiscal conservative would also limit spending to what is lawfully and constitutionally essential.
The Republican Party is NOT a fiscally conservative party. They may be somewhat more fiscally conservative than Democrats, but that is like calling an elephant svelt because it isn’t as heavy as a rhinoceros.
There are two options: Joining a fiscal conservative party like the Libertarian Party or forming your own party. I would suggest joining the Libertarian Party. It is already an established party whose platform is consistent with fiscal conservatism. And if enough fiscal conservatives join the Libertarian Party, the Democrats will have a formidable foe who will stop the excessive taxation and spending Americans have had to endure.
