Perhaps more worrisome, women don’t seem to think she’s telling the truth about her server. Among all female voters, 51% in a Fox News poll said Clinton “knowingly lied” about her private server, while 51% of women in CNN’s August survey said Clinton did something wrong when she decided to control her email through her own server.

Clinton’s slide among her core constituency hasn’t gone unnoticed by her Republican rivals. “It appears that Democratic women are starting to trend the way of the larger electorate,” said Kellyanne Conway, a longtime Republican pollster who is working for the Ted Cruz campaign this cycle. “They don’t trust her, and they don’t see her projecting confidence in herself, in them, or in the future of the country.”

Conway said that from Republicans’ perspective, Clinton would need to outperform Barack Obama’s 56% showing among women voters in 2008 in order to win a general election contest in 2016. “Knowing that women will comprise a majority of the electorate and knowing that she will under-perform among men compared to President Obama and President Clinton, she needs to get closer to 58% to 60% among women and right now she is nowhere near that.”
