Potential 2012 Republican presidential candidates who have criticized President Obama's Libya actions themselves lack very clear or coherent ideas about how to effectively deal with Moammar Gadhafi, according to Washington Post political writer Dan Balz.
The 2012 contenders want Libyan leader Moammar Gaddafi out. They want the United States to lead. They are skeptical of the role of the United Nations and the Arab League. They want no protracted engagement. But few have offered anything approaching an exit strategy.
Of course, go back to 2007 and 2008 and you'll find a pre-White House Obama saying the U.S. surge of military troops failed in Iraq. He even said the surge would worsen sectarian violence.
Once that position became an obvious political problem since facts on the ground indicated that the surge was having a positive effect, Obama shifted position.
It's the job of political candidates to paint contrasts with those they hope to succeed. Coming up with a viable alternative plan comes second, if at all.
