The three union leaders also complained their nonprofit insurance plans are still subject to ObamaCare’s new 2%-3% tax on each insurance policy. They want their members exempted from the tax every other family with health insurance must pay. Who knew labor leaders were such staunch tax opponents?

It will not help Democratic enthusiasm in the 2014 midterm elections if ObamaCare causes (a) more workers to lose their union-provided insurance and (b) their hours and paychecks to be cut. In addition, Democratic candidates could be seriously damaged if the three labor bosses follow through on their letter’s threat to stop helping elect Democrats if the law isn’t changed.

Republicans cannot just watch and jeer from the cheap seats. According to a poll last month by Crossroads GPS (a 501(c)(4) issue advocacy group I helped form), voters will respond to a focused discussion of ObamaCare’s shortcomings and a robust set of alternatives.

The GPS poll strongly suggests Republicans treat ObamaCare as a pocketbook issue: 62% believe making health care more affordable should be the top health-care priority. Among these voters, 38% say ObamaCare makes things worse while 23% say it will make things better.
