By Neil the Ethical Werewolf There's some interesting new 2008 presidential polling today. All the data comes from a sample of Iowa voters, so take it with a grain of whatever seasoning you like on corn. The pollsters took 4 Democratic candidates (Hillary, Edwards, Vilsack, and Kerry) and 4 Republican candidates (Giuliani, McCain, Frist, and Romney), and asked voters who they would choose in each of the 16 possible head-to-head matchups. Unsurprisingly, Giuliani came out as the most electable Republican candidate, beating Edwards by 8 and beating all the other Democrats by 13 or more. McCain was next -- he leads Edwards by a mere 1% margin, and no other Democrat is anywhere close. Kerry falls to McCain by 14, Vilsack by 15, and Hillary by 17. Overall, Edwards is easily the best Democratic candidate against all Republicans, beating Romney and Frist by double-digit margins. The other Democrats have single-digit leads at best. Hillary loses to everybody.
