“They’re pretty bad,” said Democratic strategist Brad Bannon, who connected the poor poll numbers to separate findings that show a broad number of Americans don’t trust Clinton.

“The No. 1 reason that her favorability is so bad is that you have large numbers of Americans who say they don’t trust her,” he said. “I could make it sound more complicated than that, but that’s really what it is. Voters see her as the ultimate politician, who will do or say anything to get elected.”

The historic comparisons are stark. At this point in the 2008 presidential cycle, then-Sen. Barack Obama (D-Ill.) was seen favorably by 62 percent of voters and unfavorably by just 33 percent. Even in February 2012, the closest comparable point in his re-election campaign, he had a net positive favorability rating in the Gallup poll of 2 percentage points, compared to Clinton’s current net rating of minus 11.

In March 2000, then-Texas Gov. George W. Bush (R) was viewed favorably by 63 percent of respondents in the Gallup poll and unfavorably by 32 percent.
