How will McCain's absence affect progress of the health bill?

Washington has rallied around Sen. John McCain after he was diagnosed with brain cancer. McCain spoke up for the first time today, tweeting "Unfortunately for my sparring partners in Congress, I'll be back soon. So stand by!" But McCain's absence is bound to affect action on Capitol Hill, including the continued wrangling over a GOP health care bill. Ed O'Keefe, congressional reporter with the Washington Post, says McCain is eager to get back in the game – and Republican Senators are anxious for his return.
