The Democrat-controlled House passed healthcare legislation. The Democrat-controlled Senate passed healthcare legislation. All Democrats need to do is settle on which version they want, then send it for a vote in their Democrat-controlled Congress. Republicans can not stop it..
Democrats are inept at almost everything they do. However, one thing that they are good at is reading polls. The American public does not want the federal government controlling healthcare, and by extension every other aspect of their lives. (Example: Obesity causes healthcare problems? The government can regulate how many calories you're allowed. That's government healthcare.).
So with the fear of being tarred, feathered, and ridden out of town on a rail, Democrats hope to muddle the perception by implying that Republicans at least partially responsible for the healthcare debacle called Obamacare. Obama arranges a summit cum photo op to show that Republicans are as bad as Democrats. All we can hope is that Republicans avoid getting splashed on.
