"When I decided to run for president, I had significantly fewer gray hairs than I do today," President Barack Obama wrote in an email to his supporters.
"Michelle says I've earned them, which is the nicest possible way to say that I'm getting older."
That phenomenon isn't unique to this president, who turns the big 5-1 on Aug. 4, just three months before the 2012 presidential election.
Supporters are invited to sign an adorable e-card — complete with a Norman Rockwell-esque photograph of wide-eyed Malia and teeny-tiny Sasha helping their father blow out his birthday candles — and/or encouraged to contribute (as little as $3, or whatever can be scrounged up) to Obama's reelection campaign.
The latter gesture comes with automatic entry into a drawing that will score one lucky supporter (plus his or her guest of choice) an invite to a celebratory get-together at the Obama's Chicago home, alongside his family and a few friends. All travel expenses included.
"We'd like to give grassroots supporters an opportunity to join in the fun," First Lady Michelle Obama wrote in campaign email. "You guys deserve it, and I know Barack would personally love to see you there."
