All of Sanders's weaknesses with only some of Clinton's strengths. Too far left, not enough experience. Will appeal to some of the Bernie wing, but a lot of the Bernie wing were Sargon of Akkad types and jfern types. The latter won't vote for someone who didn't at least back Bernie in the primary, the former have little taste for the kind of feminist message Warren offers. However, her greater loyalty to the party will give her some liberal Clinton primary voters. I don't expect Warren to do well with African American voters. Basically limited to roughly 27% of the Democratic primary vote, at the very most.
I'm not the purity troll I'm straw manned to be. I'd probably hold my nose and vote Warren if there was no better option. But many have been unimpressed at her actions as Senator versus how much more freely she criticized Hillary when she wasn't a politician yet.
Warren is barely to the right of Sanders. She's a good deal more hawkish.
I wouldn't say that. I'd say that both Sanders and Warren barely spend any time talking about foreign policy. To the extent they do talk about it though, sure, Sanders is to the left of Warren, but they're both to the left of both Obama and the median Democratic Senator. E.g., Warren voted against arming Syrian rebels a few years ago, and voted against selling arms to the Saudis last year, both votes which got the support of about half the Dems in the Senate. And both Sanders and Warren support the US attacking IS in Iraq and Syria (as does the entire DC establishment, of course), so it's not like either is any kind of uber-peacenik.
She is more hawkish. She voted for the recent sanctions bill. She voted for this increase in military spending.
