Former secretary of state Hillary Rodham Clinton remained a hot search tops for Google during Sunday night's Democratic presidential debate – but some of the questions people were asking won't please her campaign.

The top trending questions on Hillary, according to Google Trends, was: 'Will Hillary Clinton get prosecuted?'

Number 3 was: 'What did Hillary Clinton do that is illegal?'

WHAT, ME WORRY? Hillary Clinton is still a topic on everyone's minds, but for all the wrong reasons, according to a Google Trends analysis

JURY OF HER PEERS: Americans most want to know whether Clinton will be prosecuted criminally

LOYAL OPPOSITION: Anti-Clinton protesters gathered Sunday night near the Democratic debate site in Charleston, South Carolina

Questions asked about Clinton's two on-stage rivals told a different story.

More than anything else, Google users wanted to know 'Why is Bernie Sanders so popular?' indicating his polling surge as debates reveal more of Clinton's weaknesses.

And about the also-ran former Maryland governor who has played the role of Greek Chorus in the debates so far, the most burning question was 'Why is Martin O'Malley running for President?'

Google senior marketing manager Daniel Sieberg went on the air during the debate broadcast to analyze the results, linking the tough questions about Clinton to scandals linked with an ongoing terror probe.

'With Hillary Clinton we see things like, "Will Hillary Clinton get prosecuted?" – questions around the Benghazi hearings,' Sieberg said.

MOVING UP IN THE WORLD: Bernie Sanders is catching so much fire that Google users want to know why he's 'so popular'

UNDER HER SKIN: Sanders' attacks have drawn Clinton into the open where she has hammered him as a policy flip-flopper and a coddler of the gun lobby

Google reported that searches about Sanders dominated the night almost uniformly from start to finish.

Overall, he was the most-searched Democratic candidate Sunday night in 38 out of 50 U.S. states.

Clinton was tops in just 12 states, all in the northern Great Plains and in the deep South.

O'Malley was the favorite – nowhere.

Clinton's chief obstacle to being nominated for the presidency has been her own political history, intertwined as it is with her husband Bill Clinton's.

In the 1990s, Hillary was seen as a foil for the then-U.S. president in the media, an enforcer guarding his authority in the White House, and an accumulator of power in Washington.

As a U.S. senator she attracted accusations of carpetbagging since she moved to New York just days before a deadline so she could make a bid to represent a state where she had never lived.

And as secretary of state, she presided over an agency whose security lapses in Benghazi, Libya contributed to the first job-related death of an American ambassador since 1979.

HOW THE REPUBLICANS STACKED UP ON THURSDAY NIGHT Google Trends ran the same sort of test Thursday night as Republican White House hopefuls debated less than 10 miles from Sunday's Democratic site. Here are the two most burning questions on Americans' minds about each of the GOP candidates: Jeb Bush How many children does Jeb Bush have? Where was Jeb Bush born? Ben Carson What kind of cancer did Ben Carson have? How many children does Ben Carson have? Chris Christie Is Chris Christie still running for President? Where did Chris Christie go to college? Ted Cruz How long did Ted Cruz's mother live in Canada? Why was Cruz born in Canada? Carly Fiorina Will Carly Fiorina be President? Is Carly Fiorina Catholic? Mike Huckabee Is Huckabee Republican? Where does Mike Huckabee live? John Kasich Where did John Kasich grow up? How do you pronounce Kasich? Marco Rubio Is Marco Rubio squandering his most precious asset? How tall is Marco Rubio? Rick Santorum Is Rick Santorum a Republican? What does Rick Santorum do? Donald Trump How does Donald Trump lose? Where was Donald Trump born? Advertisement

She was also accused of participating in a cover-up of that Libyan jihadi attack by claiming weeks before President Barack Obama's election that it wasn't terrorism but a mod scene inspired by an anti-Islam YouTube video.

More recently, an FBI investigation is continuing to examine her exclusive use of a private email address to conduct government work while she ran the State Department.

A court-ordered dump of emails she later turned over to State – not including the tens of thousands she admitted deleting – has found more than 1,200 messages later deemed 'classified' by intelligence authorities.

Clinton remains dogged by scandal, with 59 per cent of Americans in a Quinnipiac University Poll released December 22 saying she's not 'honest and trustworthy.'
