If it fails this time, big labor will be back in 2011. The rats will likely have a filibuster proof majority. The rats do not want to vote on card check this time. Many rats are getting nervous about close ties to big labor before the 2010 elections.
Are you sure about that? I haven't looked at a state by stat breakdown, but parties with big majority, by definition, have more seats to defend. And they don't have GWB to kick around any more.
