THE HILL: Dem Anxiety Hangs Over Clinton:

Democrats are worried about Hillary Clinton’s inability to separate herself from Donald Trump in the polls, even after what they believe was a largely successful convention that represented a real step toward party unity.

Clinton is hoping for a big post-convention boost, but the reality right now is that she in behind Trump in the polls, and has been in a relatively tight race for weeks.

While the Electoral College may give her an advantage, party leaders and strategists say they remain concerned that Clinton is a tough sell when a majority of Americans think the country is on the wrong track and want to shake up Washington.

“The most important thing is there is a bias for change and there’s an NBC/Wall Street Journal poll where people express that bias even when they don’t know what the change is going to be,” said Geoff Garin, a pollster who worked for Clinton’s 2008 presidential campaign and now advises Priorities USA, a pro-Clinton super PAC.

That July survey showed a majority of voters, 56 percent, prefer someone who will bring major changes to government even if they don’t know what those changes will be. Only 46 percent wanted a candidate who would bring a steady approach to government.

It helps explain Trump’s success, and the strong challenge to Clinton in the Democratic primary from Sen. Bernie Sanders.

Away from the hoopla of the Wells Fargo, Democratic officials and strategists say it’s a major concern.

“I’m nervous. The country is in a bad mood. It’s such an unpredictable year,” said a Democratic National Committee official who requested anonymity to speak frankly about Clinton’s prospects.

Other concerns include the possibility of an enthusiasm gap between Republicans and Democrats — Trump got more votes in the GOP primary than any candidate in history while Hillary received fewer votes than she did in 2008 when she lost — and a possible “October surprise.”

One labor official fretted that more hacked emails from the Democratic National Committee may surface later in the campaign and hurt Hillary.

I think there’ll be something. But her biggest weakness is that she’s most popular when she’s not in the news, and it’s hard to run a campaign that way.
