Washington (CNN) Ohio Democratic Rep. Tim Ryan is calling his bid to oust Nancy Pelosi a "David versus Goliath" type clash -- a back bencher competing against the top House Democrat who made history in 2007 when she was sworn in as the first female speaker of the House. "If you're a quarterback and you keep throwing interceptions, you change quarterbacks," the 43-year-old Ryan, a former high school football player, said in a recent interview criticizing the record of Pelosi, 76, and arguing it's time for a younger generation to take the reins. Ryan's gambit is unusual because most leadership challenges come from members using another party position or a top slot on a key committee as a launching pad.Ryan is in his 7th term, but hasn't been a national leader for DemocratsYounger Democrats are unhappy with the lack of opportunities to advance in party leadershipPelosi is expected to fend off Ryan's challenge 
 Question:Ryan and other _ who pressed for more time before the vote point out that there is basically no bench for House Democrats.

(CNN) -- He is arguably the most well-known American general since MacArthur, and perhaps the most effective since Eisenhower. Now Gen. David Petraeus takes on what many believe will be his biggest challenge yet: reversing the momentum of the Taliban in Afghanistan and helping to stabilize the rickety regime of Afghan leader Hamid Karzai. Petraeus faced far more daunting challenges in Iraq when he assumed command there in early 2007. Those challenges, and how they were overcome, are worth recalling as he assumes command in Afghanistan, as they may provide some indicators of the way forward there. First, Iraq was embroiled in a vicious civil war in which Shia and Sunni civilians were showing up dead on the streets of Iraq's cities at the rate of 90 a day, some tortured in the most unspeakable manner, their heads drilled open.Gen. David Petraeus, who has a Ph.D. from Princeton, wrote the book on counterinsurgencyPeter Bergen says Petraeus accomplished a huge turnaround in IraqThe general took many steps to gain public support for U.S. efforts in Iraq, Bergen saysHe notes Petraeus has said Afghanistan will be harder 
 Question:As Petraeus himself has sometimes said, Afghanistan could be harder than _.
