Has there been a non-Trump lunatic president? Or one that turned the government sharply left? I hear this kind of claim pretty often and I have trouble squaring it with reality.
Even a true centrist would have built a public option along with the Affordable Care Act. Obama didn’t even support gay marriage when running in 2008! Clinton’s NAFTA accelerated American manufacturing shifting outside of the country. The craziest thing Gore would have done is combat global warming.
America is at best center-right. Our last leftist president was LBJ.
