It's turning out, too, that most women are strongly pro-life, and as the Republican message starts reaching the blacks most of them will go Pubbie too.
Most importantly, the Dems hammerlock on information has been shattered. Network news and urbane dailies no longer have a monopoly on the media and are in fact dying.
Whenever a political party allows a narrow segment of it's base to exercise a veto over it's candidates and policies it will, by neccessity, begin to shrink. That's why Reagan Democrats, gun owners, pro-lifers, etc have been moving toward the Republicans for the last 20 years. The Republicans are trying to build a big-tent party and a long-term governing majority while Democrats continue to focus on placating narrow segments of their base.
Personally, I think that, barring some major scandal or disaster, we're heading towards a long, several decade run as America's majority party. Then again, I've thought that before. Old voting habits die hard however, and baby boomers continue to be a problem. :-(
