There is Hope for Democrats in the Future
This link points to a Pew Research article from last year that shows Democrats are gaining constituents from millennials, from women, from non-whites and from people who are college educated, while the Republicans are the party of old white men, evangelicals and those with a high school level education. So as the old white men die off, the population becomes more educated and diverse, and more people turn away from Christianity, the Democrats could get an overwhelming majority. That is why the Republicans are trying to cling to power through gerrymandering, voter suppression and other dirty tricks. They would be better off in the long run if they changed their policies to appeal to more people in the middle of the political spectrum.
