Democrats, though, have increasingly fallen out of favor with the Chamber in the Obama era. In 2008, it endorsed 38 Democrats. In 2012, it endorsed five. This cycle, the Chamber has issued 260 endorsements, a total that includes just two Democrats — Reps. Henry Cuellar in Texas and Jim Costa in California. It promises that more Democratic endorsements are on the way, but it will be telling to see how much money the Chamber devotes to saving Democrats in tight races. ... In 2010, with big business rebelling against Democratic initiatives like the Affordable Care Act, cap-and-trade environmental protections and union-friendly "card check" legislation, the Chamber raised and spent $33 million on political activity, winning 87% of the races in which it endorsed a candidate.
