Sen. Sherrod Brown on Afghanistan: 'I think we've been there too long'

Brown, who will likely face a tough reelection race next year, represents a growing frustration among congressional Democrats with the war in Afghanistan, and one that's reflected in the latest polling on the war. In an ABC News-Washington Post poll released earlier this week, 73 percent of respondents said they want to see a substantial withdrawal of U.S. troops by the summer.    

In the House on Thursday, a resolution championed by Rep. Dennis Kucinich (D-Ohio) that would remove U.S. troops from Afghanistan failed, but it gained the support of over two dozen more lawmakers than had a similar effort last year, including that of several congressional Republicans. 

In addition to pressuring Obama on Afghanistan, Brown called for the president to be more engaged in the budget battle on Capitol Hill. Brown said moving toward a balanced budget means "putting everything on the table," including "a millionaire's tax" and "cuts in farm subsidies." 

The Ohio Democrat also said he's likely to favor increasing the debt ceiling when it comes up for a vote, saying, "Responsible people here will do what we need to do on the debt limit, because you go up to the precipice on the continuing resolution — you can't do it on the debt limit." 

Brown will be a top Republican target next year, but a recent poll had him ahead of all rumored GOP opponents by at least 15 points. According to numbers from Democratic-leaning Public Policy Polling, Brown leads Ohio Secretary of State Jon Husted by 15 points and he leads both Rep. Jim Jordan and Lt. Gov. Mary Taylor by 19 points.
