Here's a good piece by Andie Coller of The Politico for those who thought the card check would just go gently into that good-night. It notes that during this current Congressional recess, unions have "rolled out a national TV ad and grass-roots campaign to coincide with the congressional recess," noting, "... there is still a chance that a stripped-down version of the bill will pass this year."
Remember, when it comes to democracy, there is no compromise. Ask Neville Chamberlain.
[UPDATE]: Looks like it's the cavalry to the rescue according to this story in Monday's WSJ from Brody Mullins. The Chamber is rolling out a million dollar ad campaign in Nebraska, Virginia, Louisiana, North Dakota and Colorado. You can see the ads featured on the front page of the Chamber's YouTube channel. They're pretty good.
