Almost a quarter of Republicans think Obama 'may be the Antichrist' as 14 states sue over healthcare reforms

Americans who suggest Barack Obama should rot in hell are apparently deadly serious.

Nearly a quarter of Republicans believe the Democrat president 'may be the Antichrist', according to a survey.

An even greater number compared him to Hitler.

Just another boys' club: Barack Obama, centre on the phone, is surrounded by male aides at the White House as they plot healthcare reform this week in a new image released today. The President has been compared to the Antichrist

Mr Obama was jubilant this week after securing his £626billion healthcare reform plan.

But his triumph seems only to have inflamed his critics among the evangelical Christians from America's heartland who kept George Bush in power for eight years and have demonised his successor.

More than half of the Republicans quizzed by Harris Poll, 57 per cent, believed the president was secretly Muslim, something he has consistently denied.

And 67 per cent of Republicans who responded believed Obama was a socialist, despite his central leanings.

The startling results came as lawyers representing 14 U.S. states filed lawsuits yesterday challenging an overhaul of the country's $2.5trillion healthcare system, minutes after President Barack Obama signed the landmark legislation.

One joint lawsuit by a dozen Republican attorneys general and a Democrat claims the sweeping reforms violate state-government rights in the U.S. Constitution and will force massive new spending on hard-pressed state governments.

Virginia went to court separately, while Missouri Republican Lieutenant Governor Peter Kinder said he would like to join the suit.

The joint suit, led by Florida, was filed with a federal court in Pensacola, according to the office of Florida Attorney General Bill McCollum.

In addition to McCollum, the Republican attorneys general from Alabama, Colorado, Idaho, Michigan, Nebraska, Pennsylvania, South Carolina, South Dakota, Texas, Utah and Washington joined the suit.

The lawsuit says the law - which expands government health plans for the poor, imposes new taxes on the wealthy and requires insurers to cover people with pre-existing medical conditions - violates the Constitution's commerce clause by requiring nearly all Americans to buy health insurance.

Mr McCollum said: 'It forces people to do something - in the sense of buying a healthcare policy or paying a penalty, a tax or a fine - that simply the Constitution does not allow Congress to do.'

Mr McCollum, who is seeking the Republican nomination to run for Florida governor, said the healthcare reforms would add $1.6billion to Florida's spending on the Medicaid health program for the poor.

The Justice Department, which is responsible for defending U.S. law in court, pledged to vigorously fight any challenges to the new healthcare law.

'We are confident that this statute is constitutional and we will prevail,' said Justice spokesman Charles Miller.

The White House agreed the suits would fail.

'There have been hearings about the constitutionality of the law, and I think there's pretty much widespread agreement that it is constitutional,' Nancy-Ann DeParle, director of the White House Office of Health Reform, said.

'I think we have governors who might be aiming for higher office who are starting to just send a message.'

The suits were filed just moments after Mr Obama signed the healthcare reforms into law.

But on the most historic occasion of his presidency so far, vice-president Joe Biden managed to put his foot in it.

Gaffe-prone Mr Biden inadvertently broadcast the F-word to America after he introduced the President to sign his much vaunted health reform bill into law yesterday.

After hugging Mr Obama at a a ceremony in the White House, Mr Biden leaned in and whispered in the President's ear: 'This is a big f****** deal.'

The remark was caught on microphones recording the event that was shown live across the country. By last night, the clip was being replayed all over the internet.

White House aides seemed to be unembar****ed, with press secretary Robert Gibbs later tweeting: 'Yes, Mr Vice-President, you're right.'
