Democrats in the House of Representatives and in the Senate near-unanimously voted for the Authorization for Use of Military Force Against Terrorists against "those responsible for the recent attacks launched against the United States" in Afghanistan in 2001, supporting the NATO coalition invasion of the nation. Most elected Democrats continue to support the Afghanistan conflict, and some, such as a Democratic National Committee spokesperson, have voiced concerns that the Iraq War shifted too many resources away from the presence in Afghanistan. Since 2006, then-candidate Barack Obama called for a "surge" of troops into Afghanistan and, since 2008, Republican candidate John McCain also called for a "surge". As President, Obama sent a "surge" force of additional troops to Afghanistan. Troop levels were at 94,000 in December 2011, and are decreasing as of recent years, with a target of 68,000 by fall 2012. Obama planned to bring all the troops home by 2014.
