The premise that America is moving right is false. The republicans have been Moving far right for 40 years but the population as a whole is much more diverse and reasoned than what we see on tv.
In 20 years I bet nobody will say that anymore.....
It's not. There are a variety of measures you can use, but tell me one significant 'liberal' policy shift of the last decade, other than Obamacare, the Republican-designed private sector-based healthcare reform that passed with no Republican votes and was followed by a major Republican win the next election.
The 'tea party' is a new force in American politics that's basically the new Libertarians, that's far-right. They've purged the Republican party of liberals or moderates, and pushed pretty much all of them to the far right to try to avoid being 'primaried'. It used to be a liberal program might be 'increase spending massively on public education', now it's 'try to spend a little to keep bridges from crashing'. We can't can't even get the civil rights bill the Supreme Court gutted fixed that passed with bi-partisan support earlier.
I've long said Obama is basically a moderate Republican historically speaking. What's happened to inequlality under him? Have big banks been reigned in? Where are tax rates? We've seen the sequester and the deficit by more than half. The unprecedented obstructionism has gutted the ability of government to do almost anything. Nevermind the Supreme Court having five radical right-wing justice re-writing the constitution to allow many things including money to dominate our politics like never before.
We aren't even close to electing a progressive president. We can have a far-right or 'centrist'. Bernie Sanders would be great but has little chance. Elizabeth Warren is considered some left-wing champion simply for being against consumer fraud of tens of billions and against income inequality to an extreme degree, and she isn't running. So it's Hillary of the same family who gave us de-regulated Wall Street, the gutting of Welfare and other 'centrist' measures, or one of the right-wing nuts.
Reagan would be far too left for today's Republican party. There are studies you can find that measure these things also.
Billionare money is pushing things to the right. Things like gerrymandering and voter suppression are helping to counter the fact some voters don't agree with the far right.
