Right Turn talks to some of Mitt Romney's advisers, who elaborate on the candidate's recent suggestion for a uniform, capped $17,000 tax deduction. 

First, the plan could cap itemized deductions at $17,000 or $18,000 of income, allow the personal exemption and keep (or create) some special tax treatment for health-care expenses (e.g., a refundable credit, a health care account).

Second, the cap could be in the form of a percentage of income.

Third, as was the case in the 1986 tax reform effort, you could eliminate credits, exclusions and deductions for upper-income taxpayers.

Wonkblog's Suzy Khimm looked at the cap idea today and found that it would mostly hit the wealthy and urban homeowners.
