The demographics are already in place. In about 20 years, the majority of America’s population will belong to one or another of various minority groups.
Clearly, the Republican party needs to make inroads among these minority groups to thrive. If too many minority voters default to the Democrat party, this spells political trouble for Republicans.
The good news, though, is that many minority voters can be attracted by Republican views on issues such as national security, capitalism, taxes, individual liberty, etc. If Republicans can slice off a big enough group of these minority voters on the issues, then the Republican party will thrive in the years ahead.
How about assessing some blame where it belongs? When 90-95% of the black population, for instance, votes like socialist kooks why bother to try? Should the Republicans court that? Look at the CBC. There are 30-40 of them. Name one that isn’t a kook.
If any Republican blacks win they won’t be winning in majority-black districts most likely. Blacks have won lots of freedoms, except for the right to have an independent political thought.
Minorities, for the most part, join the mainstream eventually.
So, minorities will come into the GOP, but not necessarily as minorities. Remember, the Irish and Italians were once "minorities." Prosperous Chinese, Japanese and Korean Americans are in the process of losing their "minority-ness." So, pandering to ethnic interests will not accomplish much, apart from alienating conservatives who believe in meritocracy.
Leave the identity politics to the Democrats. Principle will win out eventually.
