It's not just Sanford who's been on the AT.
Again, for those of you trying to keep track this is what the Republican party has been doing on the AT since 2006:
September 2006: Rep. Mark Foley (R-Fla.), a fierce opponent of child pornography, resigns after it surfaces that he has sent illicit emails to teenage pages.
October 2006: Current Nevada Gov. Jim Gibbons is accused of assaulting a woman in a parking garage by throwing her against a wall and threatening to rape her. She drops criminal charges, citing intimidation by his campaign. She does, however, file a civil suit. In June 2009, Gibbons asks a judge to seal his phone records against her lawyers, something that may also have to do with his ongoing divorce proceedings, in which he's accused of more affairs.
April 2007: Randall Tobias, Bush's Global AIDS Coordinator who spoke out against prostitution (and condom use, for that matter), resigns from the State Department after he is linked to an escort service. He maintained that there was no sex, just massages.
July 2007: Sen. David Vitter (R-LA), an abstinence-only sex ed advocate, is linked to the D.C. Madam's high-end escort service. He has not resigned, and plans to seek re-election next year.
July 2007: Glenn Murphy Jr., president of the Young Republican National Federation who advised GOP-ers to use g_ay marriage as a wedge issue, is accused of trying to perform oral sex on a sleeping 22-year-old man. In 1998, a young man had filed an uncannily similar report against Murphy.
July 2007: Florida State Rep. Bob Allen, the co-chair of McCain's 2008 Florida campaign, is arrested for offering an undercover cop $20 for the privilege of performing oral sex on him. He later says he was afraid of becoming a "statistic," as he thought the black cop was a mugger. Allen previously advocated keeping g_ay couples from adopting children and applying stiffer penalties for lewd acts.
August 2007: Sen. Larry "Wide Stance" Craig (R-ID) pleads guilty in August 2007 to disorderly conduct for soliciting sex from an undercover cop in a Minneapolis airport bathroom. He refuses to resign, but does not run for re-election.
May 2008: Family values champ Rep. Vito Fossella (R-NY) ends his re-election bid after a drunk driving arrest leads to the revelation that he has had both an affair and a child with another woman.
June 2009: Sen. John Ensign (R-NV), who called on Clinton to resign and has spoken about the "sanctity of marriage," admits to an affair with Cynthia Hampton, a staffer and the wife of another Ensign staffer, whom Ensign helped to secure new employment after the affair was discovered.
June 2009: South Carolina Gov. Mark Sanford, who called for the ousters of Bill Clinton and Rep. Bob Livingston (R-LA) over their extramarital affairs, admits to a year-long affair with a woman in Buenos Aires after disappearing for a week.
Family values, baby, family values...
Also, note that the trail sees the heaviest use in the summer months.
