Demographically, culturally, fiscally, we’re hemorrhaging as a country. Studies show that most immigrants, legal or illegal, have a political predilection towards larger, more authoritarian government. They do or will vote Democrat. That’s why amnesty is the death knell for the right-leaning electorate. And amnesty is only a matter of time, which means the GOP as a nationally viable party could have an expiration date within your lifetime. Several states, including Texas, were decided by fewer votes than those states have illegal immigrants. Amnesty pushes those states blue, which then push a far Left agenda in a Democrat-controlled Congress. That writing is on the wall.
Without amnesty, studies show that larger percentages and greater numbers of future generations are slightly or consistently liberal. Millennials are the least white voting generation on record; Generation Z is less white than Millennials, and these two groups are or would vote for Leftist populists (like Bernie Sanders) in far greater numbers than previous generations. If we look at political leanings by generation (graph below), we can see the decline in percentage of those mostly or consistently conservative. (Look at each generation in 2017, for instance.) The opposite is also true: the Baby Boomer generation in 2017 had a greater percentage of mostly or consistently liberal than the Silent Generation; Generation X had a higher percentage than the Baby Boomers; and the Millennial generation has a higher percentage than Generation X. Each generation is becoming more liberal due wholly to immigration. Because immigration is little more than importing future Democrat voters, I don’t see how the GOP hangs on to anything outside of regional power without a cultural resurgence (like Reagan, for instance).
