UNITY, New Hampshire (CNN) - The day began with a kiss.
Sen. Barack Obama, on the tarmac at Reagan Washington National Airport, reached out to shake Sen. Hillary Clinton's hand and leaned down to kiss her cheek.
It went on from there. Wearing a tie that matched her suit, he put his hand on her back, guiding the way up the plane steps.
They sat side-by-side for the flight up to Manchester, New Hampshire, chatting amiably. One overheard conversation was about the plane. Clinton had used it during the primary season.
They hopped on a souped-up bus for the 1½-hour ride to Unity, New Hampshire.
The honorary mayor of Unity introduced the pair, admitting that he was a Republican who voted for John McCain in the primary. He didn't seem so sure about the general election.
They walked onstage to the tune of "Beautiful Day."
Arms around each other's waist, they smiled and waved at the crowd.
