I want readers to draw the true and obvious conclusion - that Obama broke his promise.

This is Obama's quote. The bolding is mine:

"I can make a firm pledge... 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... you will not see any of your taxes increase one single dime."

Obama did not make an exception for the cigarette tax in his quote.
