It is a fact. Nearly half of all Americans don't pay any federal income tax. Of course they pay other taxes. They can't avoid sales tax or getting a required license or local property taxes. Many pay Social Security and Medicare and many don't pay those either. But the number of those paying no income tax will fall between 47 and 51%. That is an unfortunate fact.
Now, given that a person is in that number, would they be for or against raising taxes on those who DO PAY income tax? Would they be supportive of more or less government spending on entitlements (whatever those are these days)? Would they be more or less likely to vote for The Great Promiser?
So, why then does this get notice or response or even questioning?
Romney, In MAY, Said The Truth
Then to torture the language to imply that Romney has "written off" those dependent people highlights the problem. Bringing those people into the productive economy through free market opportunity isn't "writing them off" unless you are actively building a society of serfdom.
