Obama breaks pledge by taxing tobacco?

I am not fan of smoking, but I have always wondered about sin taxes like the tobacco taxes. If you are taxing something, hoping it will make folks stop buying it, shouldn't you plan for that revenue stream to go away? Anyway, it seems a number of people are furious about the president's plan to increase taxes on cigarettes because it breaks a campaign promise that was prominent.

The largest increase in tobacco taxes took effect despite Obama's promise not to raise taxes of any kind on families earning under $250,000 or individuals under $200,000.

This is one tax that disproportionately affects the poor, who are more likely to smoke than the rich.

"I can make a firm pledge," he said in Dover, N.H., on Sept. 12. "Under my plan, no family making less than $250,000 a year will see any form of tax increase. Not your income tax, not your payroll tax, not your capital gains taxes, not any of your taxes."

I don't see this as being a major point that can be scored by Conservatives against Obama, but I do see it as potentially undermining him among his Liberal supporters.
