Obama was soon comparing Biden to a basketball player "who does a bunch of things that don't show up in the stat sheet". In May, Biden visited Kosovo and affirmed the U.S. position that its "independence is irreversible". Biden lost an internal debate to Secretary of State Hillary Clinton about sending 21,000 new troops to Afghanistan, but his skepticism was valued, and in 2009, Biden's views gained more influence as Obama reconsidered his Afghanistan strategy. Biden visited Iraq about every two months, becoming the administration's point man in delivering messages to Iraqi leadership about expected progress there. More generally, overseeing Iraq policy became Biden's responsibility: Obama was said to have said, "Joe, you do Iraq." Biden said Iraq "could be one of the great achievements of this administration". His January 2010 visit to Iraq in the midst of turmoil over banned candidates from the upcoming Iraqi parliamentary election resulted in 59 of the several hundred candidates being reinstated by the Iraqi government two days later. By 2012, Biden had made eight trips there, but his oversight of U.S. policy in Iraq receded with the exit of U.S. troops in 2011.
