If you needed more evidence that the 2016 Democratic presidential primary is not the 2008 Democratic presidential primary, here's some. A Quinnipiac poll
shows Hillary Clinton with an extremely healthy lead. Extremely healthy:
With 60 percent of the vote among Iowa likely Democratic Caucus participants, former Secretary of State Hillary Clinton has an early lock on the first-in-the-nation presidential test, apparently undamaged by a nationwide flood of negative publicity, according to a Quinnipiac University poll released today. [...]
U.S. Sen. Bernie Sanders of Vermont has 15 percent among Democrats, with 11 percent for Vice President Joseph Biden and 3 percent each for former U.S. Sen. James Webb of Virginia and former Maryland Gov. Martin O'Malley. Another 7 percent are undecided.
(Bear in mind that the 15 percent Bernie Sanders is pulling in would be a very strong show for someone in the current Republican field.)
By contrast, an August 2007 poll of Iowa put Clinton one point behind Barack Obama and tied with John Edwards. Given that Clinton has come under heavy attack in recent weeks, though, the best measure may be her against herself. She looks fine in that regard, too, with a late February Quinnipiac poll having pegged her at 61 percent in Iowa. This is just the latest poll to show Clinton's polling numbers holding up, with a NBC News/Wall Street Journal poll showing her favorability declining but stronger than that of top Republicans and a New York Times/CBS News poll showing her favorability rising.
