It is worth noting that in 2016, the Party of Lincoln gave 60% of its vote in Iowa to two Cubans and a black man. On the other side, the only contestants in play are old, white, and of varying degrees of socialism.
This is a big deal. The GOP has, for a long time, been stereotyped as the party of white men, but since the rise of the tea party, the GOP has been replacing old white men with younger politicians of varying races. The GOP still has more statewide elected hispanic officials than the Democrats.
At the same time, the Democrats, having elected the first bi-racial President, continue to pivot around Mr. Obama with more old white people and often wealthy old white people.
The GOP continues to be the party of the future and tonight in Iowa proves it.
