This shows just how slender is the real discontent among the base:
[I]n the early primary state of New Hampshire ... a Magellan poll ... tested Obama’s prospects against three hypothetical primary challengers: Secretary of State Hillary Clinton, former DNC Chairman Howard Dean and Vermont Sen. Bernie Sanders. None of the match-ups is close to competitive: “Obama would beat former Vermont Gov. Howard Dean by a 78% to 10% margin. He would beat Vermont Senator Bernie Sanders by 79% to 8%.... The only Democrat in the survey who eats into Obama’s vote share in a significant way is Secretary of State Hillary Clinton. Nevertheless, Obama would still beat Clinton handily, 59% to 28%.
Move along, folks, nothing to see here.
