Today's Washington Post includes an article about voters' misperceptions about the presidential candidates' tax plans -- an article that fails to clarify much about their actual proposals. Here's how the Post explains the distribution of the candidates' tax cuts:

If voters hear any part of Obama's message, it's his vow to treat taxpayers differently depending on their income. Under his plan, lower- and middle-income workers would see large tax cuts, while families in the top 1 percent of the income scale would see an average annual tax increase of nearly $100,000, according to the nonpartisan Tax Policy Center.

McCain, by contrast, vows to cut taxes for all families, but his plan would concentrate those benefits among the same families who would suffer under Obama. While middle-income families would see an average tax cut of about $321 under McCain, according to the Tax Policy Center, families in the top 1 percent would see an average tax cut of nearly $49,000.

Notice anything missing? The Post tells us the “average tax cut” for “middle-income families” under McCain's plan: $321, according to the Tax Policy Center. Is that more or less than such families would get under Obama's plan? That's a fairly basic question, and one you would think an article about the candidates' tax plans would answer. But the Post says only that under Obama's plan, “lower- and middle-income workers would see large tax cuts.” Well, great. How large? More than under McCain's plan? Less? The Post doesn't tell readers. Is it any wonder that voters don't understand the candidates' tax plans?

For the record, the Tax Policy Center -- the very organization the Post relied on for its information -- says Obama would give bigger tax cuts to middle income taxpayers than McCain would:

The Obama plan would reduce taxes for low- and moderate-income families, but raise them significantly for high-bracket taxpayers (see Figure 2). By 2012, middle-income taxpayers would see their after-tax income rise by about 5 percent, or nearly $2,200 annually. Those in the top 1 percent would face a $19,000 average tax increase—a 1.5 percent reduction in after-tax income.

McCain would lift after-tax incomes an average of about 3 percent, or $1,400 annually, for middle-income taxpayers by 2012. But, in sharp contrast to Obama, he would cut taxes for those in the top 1% by more than $125,000, raising their after-tax income an average 9.5 percent.
