The thing with voter suppression from the conservatives is that it's not some new thing they are coming up with as a reaction to anything. It's been part of their strategy since the inception of the USA. Blacks, Native Americans, Women, Asians, etc have all been denied the right to vote outright through everything from Congressional legislation to poll taxes, literacy tests and more. So this recent iteration is not really an indication of anything new but just a continuance of how they always do business.
And I don't buy into Raul's over-simplistic demographic determinism for a variety of reasons.
1) party identification doesn't mean people won't still vote GOP in any given election (heck just look at that graph. in 1992 or 1998, some concluded the same things Raul is now only to see a resurgence in GOP party identification)
2) there are plenty of studies that prove people do actually vote more conservative the older they get, so today's influx of youth voters that look like some permanent swing could easily turn into GOP voter majority by the time they retire in 40-50 years (if retirement is even an option for many of them)
“We can say, with a great deal of confidence, that people get more conservative when they get older—and a lot more,” says Chicago Booth’s
Sam Peltzman, who conducted the research. “It’s not just a little bit. It’s a pretty big change over their lifetime.”
Though some people form their political beliefs early in life and stick with them, most of us follow a predictable and durable pattern: our political beliefs steadily become more conservative as we age, no matter what generation we belong to or what era we grew up in, the research finds. "

The sky is hardly falling for the GOP in the long term.
