Brown could still be hoping some of the Obama magic will rub off on him with speculation he may drop by the White House to meet the Great One and steal a march on his rivals and a few votes back home.
Both Downing Street and Brown have been pinning their pre-election hopes on an April 2 London get together of "world leaders", to cash in on some of the Obamashine.
Now the Westminster Mole reports there's speculation Downing Street may decide on a Washington trip ahead of the G20 summit.
Yesterday was a bad Brown day when Blair stole a march on his old foe, sneaking in a quick prayer meeting with the other Messiah. Billed as the "first world leader to meet with Barack Obama", the sight of the best buddies must have got up Brown's nose.
Today is no better with Downing Street not a happy bunny after French president Sarkozy publicly savaged Brown and blasted his "economic mistakes".
A Washington meeting makes sense for Downing Street and Brown, who lives and breathes the election and how to wrong foot the Tories.
With the race now on to be the first or second world leader to meet the Chosen One, there are fears France's Sarkozy or Germany's Merkel could get in first.
Time and again Downing Street and Brown have been talking up the hopes of Obama's London visit. "He's working hard on that G20 summit" is how it's spun but as the Orange Party pointed out yesterday, who wants to be photographed shaking hands with a loser?
A world conference on the world financial crisis without the US President may seem unthinkable but the Obama administration works to its own agenda and such a conference may be better served with US finance chiefs rather than a personal appearance by the commander in chief.
World leaders certainly seem obsessed with trying to be seen standing shoulder to shoulder with the US President and Brown, with his plan to save the world with a painful fiscal stimulus, is no exception, to try to make Cameron look small fry.
Brown is pressing Obama to sign up to an anti-protectionist global trade deal. Also at stake is the 'special relationship'. Obama needs Brown's support to fight his war in Afghanistan and there's the vexed issue of Gitmo after revelations of an apparent CIA threat to suspend intelligence-sharing between the two allies, amid allegations of torture, with the complicity of UK intelligence.
Those issues could only be thrashed out at a face-to-face meeting.
With the credibility of beleaguered Brown in ruins both at home and abroad, best to get in quick.
A week is a long time in politics. Between now and April 2 is a lifetime.
