I'll say this on their behalf: all of those tax loopholes that they pretend they want to close in order to make their tax plan work -- but won't name before the election, and probably won't close anyway after the election, assuming they won -- probably should be closed. They're all things most economists agree are inefficiencies that distort the market and we’d be better off without them.
Here's the thing: you can rarely get rid of any benefit the government gives to its citizens. Whether it's farm subsidies or home mortgage deductions or Medicare prescription drug benefits that aren't paid for or defense contracts, once they're given, they're almost never rescinded. And they add up.
But at least they're talking about closing them (while not talking about closing them). It's slightly more than the Democrats do.
There. I said something nice about Mitt Romney and Paul Ryan.
