The Democratic Party will be the party of Hispanics, African Americans, and Muslims. It will continue to support neo-liberal economic positions as its support for open borders (the wedge issue which will eclipse even abortion) makes social democracy impossible. They may actually come to officially embrace social democracy at some point but by that time the country will be so poor and overpopulated due to immigration that services will be crap.
The Republican Party will become the party of White people. While the majority of super rich will still be White, most White people will end up becoming poorer than the average minority, due to relentless diversity pushes and immigration forcing down wages in general. Most rank and file Republicans will be openly and actively racist. The party leadership will probably be more reserved and simply call for racial hiring quotes, which would be less detrimental to Whites than constantly favoring minorities in every hiring. The fact that everyone in the future will be pro-gay marriage and pro-choice will make it easier for pro-immigration conservatives to leave for the Democratic Party.
I hope you're joking.
If not, you deserve to be ridiculed for actually being this stupid.
What's stupid about it? You're from New York. You have seen the future. The future is New York City/LA/Dubai. A country where most people are poor and/or foreign born but there's enough mega rich people that it throws the averages off and hide the fact that the place is third world.
