A little earlier I posted on an ABC News – Washington Post poll that verified the trend of Hillary’s crashing level of support. But the reason for the rapid descent is a direct threat to Hillary’s viability.

Her support in the primary has tanked in particular among women, previously a mainstay of her candidacy, from 71 percent in July to 42 percent now.

This is a trend that has been noticed among Democrats. Via The Daily Beast, Why Are Women Ditching Hillary?

The Clinton campaign went into overdrive this week to shore up support among voters most assumed would have been locked in as Clinton backers from the start—Democratic women.

From last Saturday’s kickoff of “New Hampshire Women for Hillary,” to Clinton’s appearance on the Ellen DeGeneres Show last Thursday where she pitched, “If you vote for somebody on the merits, one of my merits is that I’m a woman,” to an online campaign store newly stocked with lady-friendly merch (official “Women’s Rights are Human Rights” tote, anyone?) the not-at-all subtle message is this: Hey ladies, vote for Hillary!

The female hard sell is coming as a series of local and national polls show that Clinton’s strength among Democratic women voters has continued to steadily, and in some cases, precipitously erode as her campaign has become bogged down in questions over use of a private email server and Sen. Bernie Sanders has risen on a wave of populist support that the Clinton camp had mostly dismissed or ignored.

The article goes on to hypothesize:

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.

Apparently, the Clinton campaign is shocked that women can actually read and that they have the capacity to process what they have read. It should be no surprise that when a majority of a demographic segment believes a politician is a liar and has engaged in misconduct that a majority will also vote for someone else.

This erosion morphing into avalanche of women voters away from Clinton is lethal. There is no way anyone in the race is going to generate black voter turnout and roll up the 97% or so level of support that did Barack Obama.

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 [mc_name name=’Sen. Ted Cruz (R-TX)’ chamber=’senate’ mcid=’C001098′ ] 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.”

If she goes into the general election with a non-existent difference in support between men and women she will be routed.
