Say whatever you want about Romney's tax numbers not adding up, the objective of the left in America is to raise taxes on the middle class, precisely because government spending as projected going forward cannot be paid for without it.
So Jonathan Cohn, here:
To reiterate something I've said before, I happen to support higher taxes for the middle class, at least over the long term, assuming they are part of a balanced deficit reduction approach that preserves Medicare, Social Security, and other critical programs. In an ideal world, Obama would make a case for precisely that sort of agenda, because without those higher taxes (above and beyond taxing the rich, as Obama has proposed) government won't have enough money to fund future spending obligations. But it's hard to fault Obama for not presenting the full facts about fiscal tradeoffs when the other side has shown repeatedly that it doesn't care about facts at all.
Conservatives need to make the point that government spending even at Rep. Paul Ryan levels is unaffordable without tax hikes on the middle class.
All the talk in the Republican Party about broadening the tax base is really about eliminating tax loss expenditures in order to raise revenues. In other words, taking away the deductibility of mortgage interest expenses, state and local income tax expenses, and the like. If it walks like a tax increase and talks like a tax increase, it's a tax increase, whether it's brought to you by the Gang of Six, the Gang of Twelve, or Mitt Romney.
The Stupid Party is about to vote for this again and the left knows it, which is why they are so happy. People like Jonathan Cohn know a Romney presidency will help achieve their goal, so it really doesn't matter if Obama loses. Unless conservatives take over the Republican National Convention and give the nomination to someone who will actually protect the middle class, taxes on the 66 percent of America which earns less than $100K per year are going up, up, up.
Conservatives need to remember what happened last time we fell for this gimmickry. Ronald Reagan agreed to eliminate deductibility of consumer interest in the 1986 tax reform in exchange for lower rates. We lost that deductibility and got the lower rates, but when Democrat Bill Clinton raised taxes in 1993, we didn't get back the deductibility. The same thing will happen again. We'll sacrifice deductibility of something else in exchange for lower tax rates, which liberals later will succeed in raising the next time they have power, putting the middle class even farther behind than it is now.
We didn't get back the deductibility lost in 1986 under George Bush in 2001, and we won't in future if we answer the siren call of broadening the tax base again.
