NBC News, however, reports that the poll includes “two cautionary notes” about Clinton:

“One, 62% of Democratic primary voters want her to have a challenging primary to test her for the general election, signaling they don’t want a coronation to the nomination.

“And two, the poll shows a generic Democrat defeating a generic Republican in the 2016 presidential race by just three points, 39% to 36%, suggesting that the general election will be competitive.”
