The Republican political party is a Moscow-influenced, loosely organized group of corrupt, mentally defective criminals, cowards, cuckolds, liars, racists, perverts and fascists. Moscow installed one of them as "president" of the former United States of America in 2016. That geopolitical entity is now known as Amerika 2.0. There is no chance of any challenger to Trump in 2020 from within that organization being other than corrupt, brain-damaged, & etc.
