A growing proportion of Americans have negative views of Hillary Clinton, according to new polls, even as the former Secretary of State remains the overwhelming favorite for the Democratic presidential nomination.

The CNN/ORC survey released Tuesday showed that more Americans now have an unfavorable view of Clinton than at any time since 2001. Fifty percent of Americans say Clinton does not inspire confidence, up from 42% in March of 2014. Fewer think she cares about people like them. And a growing number of people, now up to 57%, do not consider her honest and trustworthy.

An ABC News/Washington Post poll released Tuesday found similar drops in Clinton’s trustworthiness. And while Clinton remains the prohibitive favorite in the Democratic primary race, the gap between her and top Republican contenders is shrinking, according to the CNN poll. In head-to-head match-ups with Republicans, Clinton is facing a stiffer challenge Marco Rubio, Rand Paul, Scott Walker and Jeb Bush than in previous surveys.

The CNN/ORC poll of 1,025 American adults, conducted between May 29 and May 31, has a margin of error of plus or minus 3 percentage points.
