No insurance? Beware of the tax man!

The Republican National Committee launched a new ad attacking health care reform as a big tax increase.

"Barack Obama and Democrats promise that health care reform will lower costs, but their plans deliver increased taxes," the ad says, adding "they've even proposed a tax for not having health insurance."

The tax in the Democrats' bills won't affect anyone who has insurance. But if health care reform passes, it will be an issue for those who don't have insurance.

The tax is the mechanism that Democrats want to use to prod people to get health coverage. If they fail to get insurance, they would have to pay it.
