PHILADELPHIAThe image younger voters have of Hillary Rodham Clinton has dropped like a rock and is now at the lowest level ever.

A new survey from Gallup found that just 31 percent of millennials have a favorable opinion of the Democratic nominee and first woman chosen by any party to run for president.

The low rating is a huge hurdle to Clinton getting the keys to the White House and many Democratic advisors are worried that she is failing to connect with younger voters.

Secrets, for example, sat with four young Democratic voters at a breakfast event Thursday, and only one said they wanted to vote for her. At a Harvard University Institute for Politics youth town hall here Secrets attended, most Clinton supporters said they were not enthusiastic about her.

Gallup said that support from younger voters is the lowest for Clinton of all age groups and has dropped 10 points in a year.

Said Gallup:

Gallup tracking over the past month (July 1-27) shows that 31% of 18- to 29-year-old Americans have a favorable view of Clinton, compared with 40% of 30- to 49-year-olds, 41% of 50- to 64-year-olds and 39% of those 65 and older. In other words, Clinton has the least favorable image among young Americans — a flip from where it was one year ago when 47% of 18- to 29-year-olds said they had a favorable image of her, at the time higher than all of the older age cohorts.

The big shift in views of Clinton among this age group occurred in February and March of this year when young Americans' positive impression of Clinton fell below that of the other age groups, where they have stayed ever since. Clinton's image has dropped among all age groups but has fallen the most with young Americans.
