The Democratic presidential candidate is viewed unfavorably by 48 percent of likely voters, compared with 37 percent who view her favorably.

Her ratings are down significantly from the last NBC/Journal poll in June, when 44 percent viewed Clinton favorably versus 40 percent who viewed her unfavorably.

These numbers will certainly add to the consternation already permeating Democratic circles following a recent Quinnipiac University poll that showed Clinton’s favorability drowning in key swing states.

Pollster Bill McInturff compared Clinton’s campaign to a battleship able to withstand several torpedo strikes, “but there has been a torpedo that has hit something, and there are some leaks.”

Despite her low favorability numbers, Clinton remains the clear frontrunner among the current field of Democratic presidential candidates.
