This is an angle that didn't occur to me, but could be really powerful if mentioned on conservative talk shows:

You hear a lot about how small businesses would get crushed by raising taxes on the wealthiest 1%, or how small business will be crushed by excessive regulations, or how small business would be crushed by a carbon tax or cap & trade. But those same people who claim to stand up for small businesses disappear when we're dealing with something that does crush small businesses - the no-win scenario of either letting the employees who feel like your family go without benefits, opting for the "split the baby" solution of getting a high-deductible or high cost-sharing plan that you know will be insufficient, or subjecting to yourself to the slings and arrows of outrageous insurance monopolies, where the only safe prediction is that your costs will go up.
