I'm not sure she'd be doing as well as he is, which is surprising. I think the fact that Bernie openly identifies as a socialist and doesn't run away from it pours gasoline on the fire of his base, the highly educated white progressives that have a major online presence. However, Bernie also appeals to the rebellious Ron Paul crowd (notice that whatever excitement/online following/comment spam crew Rand Paul had has fizzled out since Sanders has gained momentum.) Warren would be "just another liberal" to this crowd.
Worst meme.
The idea of Ron Paul supporters who were a mix of Paleoconservatives and Libertarians. liking bernie sanders is mainly based on a misunderstanding that they were attracted to Ron Paul only mainly because of non-interventionism when Ron Paul had a strong pull from ultra-free market believers. Of which i doubt bernie is getting support from.
Ron Paul received a great deal of support from Libertarians, but I can attest being a socialist who changed my registration to Republican to vote for Ron Paul in the primaries, because Ron Paul (a much better person and campaigner than his son, by the way) was the only mainstream candidate who was speaking out against policing the world. Ultimately, I ended up voting for Romney because I liked the man, and also as a protest vote against Obama.
You're a socialist whose big issue is less military intervention and you voted for Romney?
I really wish Manchin would run. He'd have my vote.
