It became painfully obvious when Trump was elected that the GOP had no intention of fixing anything, they're only interested in being an opposition party because that's where the money is. The voters gave them the presidency, senate, and house with a mandate to get rid of the disastrous Obamacare and stop the invasion at our southern border. Trump's agenda was to fix both and both chambers of congress stonewalled him at every turn.
About 90% of the GOP needs to be tossed out on their ass. They're nothing but a bunch of lifelong politicians getting rich off of kickbacks and bribes while pretending to represent their constituents and doing exactly the opposite of the rhetoric they spew.
