Who's Opposed to Healthcare Reform?

Tampa, St. Louis, Houston, Austin, Denver and Milan, Michigan are just some of the cities to see rowdy protests in the past few hours. White House aides told Senators on their way home for the August recess, "If you get hit, punch back twice as hard." But the Democrats are still squabbling over details, so there's no coherent message either for them or a President whose approval ratings are on the decline. The Republican message is "just say ‘No'" to some variation of "socialized medicine." Could the protests backfire? Will the Democrats strike back in kind? When the August recess is over, will it be too late for the President to reset the agenda?
