Clinton's standing fell even more among Independents, Democrats and young adults since April. Her favorability fell 11 points among independents, from 46 percent to 35 percent, and 12 points among Democrats, 88 percent to 76 percent. Her standing among young adults age 18 to 34 saw the biggest drop. Just 38 percent of young adults surveyed view her favorably, while 53 percent view her unfavorably.
Clinton fared well in comparison to New Jersey Gov. Chris Christie (R) and Sen. Ted Cruz (R-TX), two potential Republican presidential nominees in 2016.
Thirty-three percent held a favorable view of Christie and 19 percent held a positive view of Cruz.
