Robert Reich said it right in this Huffington Post article:
It's as if they didn't learn a thing from the 2012 elections. Republicans are on the same suicide mission as before -- trying to block immigration reform (if they can't scuttle it in the Senate, they're ready to in the House), roll back the clock on abortion rights (they're pushing federal and state legislation to ban abortions in the first 22 weeks), and stop gay marriage wherever possible.
As almost everyone knows by now, this puts them on the wrong side of history. America is becoming more ethnically diverse, women are gaining economic and political power, and young people are more socially libertarian than ever before.
Why can't Republicans learn?
It's no answer to say their "base" -- ever older, whiter, more rural and male -- won't budge. The Democratic Party of the 1990s simply ignored its old base and became New Democrats, spearheading a North American Free Trade Act (to the chagrin of organized labor), performance standards in classrooms (resisted by teachers' unions) and welfare reform and crime control (upsetting traditional liberals).
The real answer is the Republican base is far more entrenched, institutionally, than was the old Democratic base. And its power is concentrated in certain states -- most of the old Confederacy plus Arizona, Alaska, Indiana, and Wisconsin -- which together exert more of a choke-hold on the Republican national party machinery than the old Democrats, spread widely but thinly over many states, exerted on the Democratic Party.
These Republican states are more homogenous and conspicuously less like the rest of America than the urbanized regions of the country that are growing more rapidly. Senators and representatives from these states naturally reflect the dominant views of their constituents -- on immigration, abortion, and gay marriage, as well as guns, marijuana, race, and dozens of other salient issues. But these views are increasingly out of step with where most of the nation is heading.
I basically agree that the GOP is on a kamikase mission toward oblivion. Do you agree?
