Fmr. Sen./SoS/FLOTUS Hillary Clinton (D-NY)Fmr. Sen. Jim Webb (D-VA)Fmr. Gov. Martin O'Malley (D-MD)Fmr. Gov./Sen. Lincoln Chafee (D-RI)And this is being quite generous to Webb/O'Malley/Chafee, as I could plausibly see a 50-state blowout by Clinton. As shown in the map, Webb could potentially get a couple states off of Blue Dog appeal, strong dislike for Clinton in WV, and being from VA. He might also be able to make states like TN remotely competitive, but hardly. I have O'Malley winning Maryland, somewhat out of pity, but Clinton could easily win there. O'Malley is the only one ideologically who could really stand a chance with the national Democratic electorate (Webb and Chafee are just too conservative), but he's so generic and unable to generate hype to the point where he wouldn't really get anywhere even though his policy positions could be popular. Chafee could win RI if he's lucky but get absolutely crushed everywhere else.
