Did Obama lie about not raising taxes?

I read Barack Obama's lips ... and he said he would not raise taxes on middle class Americans. Did he lie to the American people?

Investor's Business Daily wondered:

Trustworthiness: The media savaged President George H.W. Bush for breaking his tax pledge. Will President Obama instead get a pass for breaking trust on middle-class taxes and medical care?

Obama is spending this country into a debt that will saddle our children and grandchildren for generations to come ... so has he decided new taxes are the way to pay for his extravagant programs? IBD asked:

Could Obama have been elected president without promising not to raise taxes on the middle class? Would Americans have trusted him with the highest office in the land if he had proposed replacing all private health insurance with a Euro-style, socialistic, single-payer system?

As Ben Stein put it in his American Spectator diary, "The American people in their unimaginable kindness and trust . . . wanted so much to believe Barack Obama was somehow better and different from other ultra-leftists that they simply took him on faith."

Did the president shrewdly mislead Americans last year regarding his true intentions?

"I can make a firm pledge," he said in Dover, N.H., in September. "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." He vowed: "You will not see any of your taxes increase one single dime."

Not one single dime, eh? Why do I not believe that?
