No matter what polls say about tax fairness, the Republican presidential candidates all say calls to tax the rich fall flat with them.
Former House Speaker Newt Gingrich said in a GOP debate Thursday night that government should shrink to fit tax revenues. And he wants something akin to a flat tax.
Former Pennsylvania Sen. Rick Santorum favors two tax brackets with the top rate of 28 percent, the upper end when President Ronald Reagan was in charge.
Texas congressman Ron Paul says he wants to get rid of the constitutional amendment authorizing a federal income tax.
Tax fairness is expected to be a major general election theme. Democratic President Barack Obama says the wealthy should pay the same share of their income in taxes as those at lower rungs.
