Hillary Clinton ducked criminal charges in the scandal over her private email server — but she couldn’t escape the wrath of voters.

A trio of new polls released Wednesday show Clinton took it on the chin after FBI Director James Comey described her handling of classified material in her emails “extremely careless.”

A national McClatchy/Marist poll said Clinton now leads Trump by only 3 percentage points, 42 to 39 percent.

It was the first time her support dropped below 50 percent in polls going back a year, and a big drop from a Marist poll April 7 that showed the former fist lady leading 50 to 41 percent.

“The good news for Hillary Clinton is that despite a very rough week, she still has a narrow edge,” Marist pollster Lee Miringoff said.

“The bad news is these issues don’t seem to be going away.”

Separate polls by Quinnipiac University found Clinton losing ground in two of three key swing states.

Trump was ahead in Florida 42 to 39 percent, a big shift from last month when Clinton led 47 to 39 percent.

Trump also had the edge in Pennsylvania, 43 to 41 percent, while the pair remained deadlocked in Ohio 41 to 41 percent.

“Donald Trump enters the Republican Convention on a small roll in the three most important swing states in the country,” said Peter Brown, assistant director of the Quinnipiac poll.

Voters in the three states said Clinton was more intelligent than Trump and was better prepared to be president. But she lost her lead on the question of having “higher moral standards.”

An NBC News/Wall Street Journal/Marist poll also found Clinton ahead of Trump in Iowa, 42 percent to 39 percent. But in the same poll in January, she had an 8-point lead over Trump, 48 to 40

percent.

Experts said Comey’s takedown was a big factor but that other forces were also at work.

“No question the polls released this week reflect the ‘Comey punch.’ How could they not? It’s a rare day when a presidential candidate is dressed down by the director of the FBI,” said

University of Virginia political scientist Larry Sabato.

“But I have to add a big note of caution. Polls right now are even more ephemeral than usual–dust in the wind. We are about to enter the biggest two weeks in this year’s politics, the

conventions and VP rollouts.

“ I want to see the polls after the convention bumps fade–about two to three weeks after the Democratic convention adjourns. In other words, mid-August.”

Princeton University political scientist Julian Zelizer said the falling numbers reflect more than just Comey’s criticism.

“She is a public figure who has been directly or indirectly the subject of investigations for decades. Though most of this is partisan, it still influences public opinion,” he said.

“ Second, the Clintons are tough politicians and this involves flexibility and compromise. This leaves many liberals frustrated and gives material for the GOP to attack. Finally, there is an element of gender bias at work here where some voters more critical of actions than they would be with a male candidate,” Zelizer said.
