Hmmm.
Blue, blue, blue, red, red, blue, blue, red, red, blue, red, red, red, blue, blue, red, red, blue, blue, red.
That of course is a list of Republican and Democrat presidents by color (red or blue), starting with FDR.
From that list, I'm not seeing a pattern that would suggest that we are having our last Republican president.
That said, with voter fraud, changing demographics, a surviving Deep State, and a corrupt Big Media and Big Tech, all working against the interests of a sovereign, free America, I'm not that optimistic.
Illegal immigration will need to stop, voting fraud will need to stop and Big Media's and Big Tech's strangle hold over public discourse will have to change.
The Deep State still needs to be punished.
Second generation hispanics and blacks will need to start voting pro American and pro freedom in greater percentages.
Republican presidential candidates (like Trump 2020) will need to start holding rallies at big arenas in big cities, in red and purple states. They will need to articulate a pro American and pro freedom message.
What are the chances of all that happening?
FDR served 3+ terms and the Truman finished one and had one of his own.
