Polling released by Rasmussen Tuesday show’s the “Hillary meter” dropping dramatically.

Rasmussen explains:

Last month, we introduced this year’s edition of the Hillary Meter to regularly update public perceptions of the former first lady on her march to the White House. Why a Hillary Meter and not one for, say, Jeb Bush or Donald Trump? Because for one thing, Clinton is far and away the leader in the race for next year’s Democratic nomination, while the winner of the Republican race is anyone’s guess. Secondly, the former first lady, U.S. senator and secretary of State is an internationally known and highly polarizing figure – greatly admired by many on the left, extremely disliked on the right – who may end up being the nation’s first woman president.

The Hillary Meter is not indicative of who surveyed likely voters want, but rather who they believe will win. Also of note is that individuals surveyed are likely voters and not registered voters. Likely voters tend to (but not always) have a lower propensity for election day turn out. Though the Huffington Post argues that if 2014 is indicative of future elections — that distinction might not make much difference any longer.

Rasmussen’s current Hillary meter:

It would seem likely voters find FBI investigations and toilet-side servers detrimental to Hillary’s inevitability:

In the face of increasing legal questions about the safety of secrets on the private e-mail server she used as secretary of State and of a vigorous intraparty challenge from Bernie Sanders, belief that Hillary Clinton is likely to be next year’s Democratic presidential nominee has dropped noticeably over the past month.

The latest Hillary Meter shows that 63% of Likely U.S. Voters believe that Clinton is likely to be the next Democratic presidential candidate, but just 26% say it is Very Likely. That compares to 78% and 43% a month ago. Thirty percent (30%) consider that outcome unlikely, with 11% who feel it is Not At All Likely. That overall figure is up 10 points from the previous survey.

Among likely Democratic voters, 74% think Clinton is likely to be their party’s nominee, but that’s down from 87% in the previous survey and 93% earlier in July. Eighteen percent (18%) of Democrats think Clinton is unlikely to be the nominee. The latest findings include 35% who say Clinton is Very Likely to be the nominee, down from 53% a month ago, but still just four percent (4%) who say that scenario is Not At All Likely.

And so Hillary’s stock continues to plummet. Potentially more devastating? Hillary hasn’t testified before the House Select Committee concerning her email handling yet. That hearing is currently scheduled for October 22.
