Actual information

A report on the candidates' tax plans by the nonpartisan Tax Policy Center has been making the rounds today (via Paul Krugman's blog). Some highlights:

1. Both McCain and Obama would greatly increase the national debt, although McCain's plan would increase it by roughly 40% more than Obama's:
   

   ...without substantial cuts in government spending, both plans would sharply increase the national debt. Including interest costs, Obama would boost the debt by $3.5 trillion. McCain would increase the debt by $5 trillion.

2. Lower/middle income families would see their after-tax incomes rise under both plans:
   

   [Obama plan:] By 2012, middle-income taxpayers would see their after-tax income rise by about 5 percent, or nearly $2,200 annually.
   [...]
   McCain would lift after-tax incomes an average of about 3 percent, or $1,400 annually, for middle-income taxpayers by 2012.

3. Those in the top 1% will experience lower after-tax incomes under Obama's plan, but significantly higher after-tax incomes under McCain's plan:
   

   [Obama plan:] Those in the top 1 percent would face a $19,000, or 1.5 percent, reduction in after-tax income.
   [...]
   But, in sharp contrast to Obama, [McCain] would cut taxes for those in the top 1% by more than $125,000, raising their after-tax income an average 9.5 percent.
   
   

4. Significantly more people will have health insurance under Obama's plan than McCain's plan, but neither plan offers universal coverage:
   

   TPC projects the McCain plan would trim the uninsured by 1 million in 2009 and nearly 5 million by 2013, although their numbers would slowly rise thereafter because the tax credit would fail to keep pace with premiums. Obama would reduce the uninsured by 18 million in 2009 and 34 million by 2018. Even under the Obama plan, however, 34 million Americans would still lack insurance in 2018.
