Interesting article in today’s Washington Post:  Alternative Minimum Tax Targeted Democrats Seek Fix For Middle-Class Families, by Lori Montgomery:

Democratic leaders this week vowed to make the alternative minimum tax a centerpiece of next year’s budget debate, saying the levy threatens to unfairly increase tax bills for millions of middle-class families by the end of the decade….

The focus on the AMT is hardly surprising, given that victims of the tax have been concentrated in high-cost urban areas such as Washington, New York and San Francisco — places that tend to vote Democratic. Rangel, Hoyer and Nancy Pelosi (D-Calif.), the presumptive House speaker, all represent states hit hard by the AMT, which is sometimes called the "blue-state tax." To map states with the highest concentrations of AMT taxpayers is to draw bull’s-eyes over California and the Northeastern seaboard.

Update:  Ann Althouse is not impressed.
