Another social networking embarrassment for a presidential candidate: Rudy Giuliani’s 17-year-old daughter Caroline supports Barack Obama for president over her father. Until this morning she was a member of the One Million Strong For Obama Facebook group, and lists her political views as “liberal.” Caroline removed herself from the group after Slate emailed her about it, but it remained in her newsfeed.

This is certainly not the first time social networks have been a thorn for political candidates. In March, Senator John McCain’s MySpace profile was hacked to suggest he was in favor of gay marriage. The incident was later picked up by the Daily Show.
