That's because over time, liberals win. That's because the victories of liberals/progressives have moved the country to the left since 1960. The battles that the conservatives were fighting at the time have mostly been lost. As will most of the battles conservatives are fighting today be lost.
That's what progress does. It rolls over those who lie in its path.
how very nice for you....how has it all turned out btw?
Actually pretty well. Since the 1940s to about the 1980s the United States experienced a huge growth of the middle class. And with that, growth in technology and industry. That kinda got Kiboshed starting with Ronald Reagan...who's idea of "growth" was sloshing money from one pocket to another. But to be fair the pragmatism of the first George Bush kinda got us back on track and helped Clinton usher in a new era of growth. To bad about his son..who screwed the pooch royally.
