Hillary Clinton sure is ambitious. She hasn't won the Democratic nomination for the 2008 presidential race as yet. But she has already set herself a bold goal for her second term in the White House!

If former president John F. Kennedy pledged to put a man on the moon in a decade, Clinton had a more down to earth proposal.

'I want to have universal health care coverage by the end of my second term' she announced at a Democratic presidential forum neatly sidestepping a debate on the second most talked about issue after the Iraq war.

There is another equally lofty story doing the rounds though unlike this one it hasn't come from the horse's mouth. There has been some media speculation that if Hillary makes it to the Oval Office, husband Bill may take her place in the Senate.

Under the American system, he can do so without contesting an election if the State's Democratic governor obliges. For under the rules, he can nominate anyone to take her place until the next election cycle in Nov 2010.

If that happens, Bill Clinton would become only the third 'Mr. President', as former US chief executives continue to be called, to go back to the Capitol Hill. Earlier, Andrew Johnson went to the Senate after his term was over, and John Quincy Adams served in the House of Representatives. William Howard Taft was the only president to become chief justice.

But would Bill fancy a return to the upper chamber? For in the six years since leaving the White House with a debt of $12 million in legal charges, he has earned an estimated $40 million in speaking fees. And words of wisdom are certainly not that expensive up on the Capitol Hill!
