THE TELEGRAPH: Barack Obama's track record has come under growing scrutiny as the senator for Illinois moved closer to the Democratic presidential nomination.
While the 46-year-old senator was boosted by the endorsement of Chris Dodd, a leading Democrat senator who dropped out of the nomination race last month, he faced criticism that during the campaign he has shifted towards the centre from the Left of the party.
Critics are increasingly asking in what direction he will lead the country if he wins the nomination and election in November.
The Washington Post said that the candidate remains an enigma.
"Is Mr Obama a standard liberal clad in the soothing language of inclusiveness? ... Do voters understand where, exactly, he would like to lead them?" it said.
He is also facing criticism for being too liberal from Republicans, who expect to be fighting against him soon for the White House.
His rival Hillary Clinton was expected to pick holes in Mr Obama's record and his lack of experience in their final scheduled debate on Tuesday night in Ohio.
She has spent the past few days mocking his "celestial" rhetoric, accusing him of misleading voters and comparing his foreign policy inexperience to President George W Bush. Barack Obama's track record under scrutiny >>> By Alex Spillius in Washington
