The contrast between JFK -> Nixon is an interesting comparison to Obama - > Trump.
Reaction couldn’t be starker. Both benefited from new technologies.
Schumer, Pelosi, etc were pro-border until recently
The left has been typically more anti immigration due to perceived impact on labor & union influence—Immigrants taking jobs from Americans.
Remember the democrats were party of south and segregation until LBJ (Lincoln was a republican— confederates were democrats).
Recently, Democrats became party for the elites, while republicans picked up working class.
The democrats built a coalition of highly educated coastal elites working in finance, media, & tech, + the identity groups
The republicans picked up old money & the working class & the libertarians & the religious
This reversal happened before. (h/t @balajis for this framework):
Zooming out:
In 1865, republicans gained moral authority from winning civil war.
Over time, moral authority turns to economic authority.
Democrats realigned as party of poor under FDR, republicans start losing moral authority.
By 1965, democrats regain moral authority from civil rights.
Democrats turn moral authority into economic authority.
Despite each version having its own idiosyncrasies...the cycle continues.
Will be interesting to see what happens next...
