Barack Obama Fist-Bumps White House Cleaner, '36 Days To Win This' (PICTURE)

With a solid lead in the polls, Barack Obama is due to face Mitt Romney in the first presidential debate on Wednesday evening.

If the latest picture of the president posted by his campaign's popular Twitter account is anything to go by, Obama seems pretty relaxed about the whole thing.

"Thank you for all you've done for this campaign, and all you'll do in the next 36 days to win this," he tweeted.

The friendly 'fist-bump' greeting was infamously nicknamed a "terrorist fist-jab" by a Fox News presenter during the 2008 presidential campaign.

Obama also used the twitter account to reveal that his campaign reached 10,000,000 donations in 2012. An achievement the campaign said was a "huge milestone and a historic record for grassroots politics".
