Hillary Clinton continues to lead all comers when it comes to potential 2016 presidential matchups, but the same cannot be said for Vice President Biden.
A new Quinnipiac University poll shows Clinton leading both former Florida governor Jeb Bush (R) and Sen. Rand Paul (R-Ky.) by eight points.
Biden, though, trails Bush by six points -- 44 percent to 38 percent -- and trails Paul by a smaller margin, 43 percent to 39 percent.
Perhaps as interestingly, positive views of Clinton have tailed off considerably in recent months, as the former secretary of state has been a focal point of the debate over Benghazi.
Quinnipiac shows her favorable rating dropping from 61 percent in February to a pretty pedestrian 52 percent. At the same time, unfavorable views of her have risen from 34 percent to 40 percent.
It remains to be seen whether other pollsters will show her numbers falling as significantly as this poll.
Biden's personal image has also suffered in recent months, with 37 percent viewing him favorably and 44 percent unfavorably. Bush has a 29/29 split, and Paul is in positive territory at 32/24.
