I'm not sure about just how "radical" these candidates are. If we are talking specifically about Bernie, I can only go by the results of the primaries. Here's
NYT reporting.
Florida was 141-73 in favor of Clinton, Georgia 73-29 Clinton, Alabama 44-9 Clinton. However, Missouri 36-35 Clinton, New Mexico 18-16 Clinton, Arizona 42-33 Clinton, Kansas 10-23 Sanders, Oklahoma 17-21 Sanders, Indiana 39-44 Sanders. I'm not saying Sanders won a lot, but I wouldn't right off radicals completely.
Is it though? Right now people are spamming Internationalist, Globalist, and Neoliberal around. Not Socialist.
The question is, will they vote as long as it's a D. I'm pretty sure many people will vote D just to prevent Trump from getting re-elected.
GND is better than the massive Trump tax cut. I'm pretty sure it'll never get past it. The good thing about GND is that even if some sections are passed, that's already a good thing. Well, depending on which sections. Some GND policies are simply pipe dreams with no grounding in reality. Cutting out fossil fuels is impossible for starters.
