Be nice to the people you meet on the way up

Because you'll meet them again on the way down, as Mitt Romney has now discovered -- he shouldn't have said all those mean things about Jimmy Carter:

James Carter IV has come forward as the online sleuth who tracked down undercover videotape of Mitt Romney's damning comments four months ago to a US$50,000-a-plate Republican fundraiser in Florida....
For Carter, his mission was personal — the 35-year-old online researcher, currently looking for work, said he'd grown sick and tired of Romney slagging his 87-year-old grandfather, a Nobel Peace prize winner who has long worked towards peace in the Middle East.
..."I don't like criticism of my family," the younger Carter told NBC News on Tuesday after it emerged he'd persuaded the fundraiser attendee who secretly taped Romney to hand the video over to Mother Jones magazine.
"It gets under my skin. I'm proud of my role in being able to track it down. My motivation is to help Democrats get elected."
In an interview with The Associated Press, he added: "I've gotten a lot of Twitter messages from people supporting me and saying that it's poetic justice that it was a Carter that uncovered this, considering the way that the Romney campaign has been talking about my grandfather. I agree with that sentiment wholeheartedly."
