House Finance Committee Chairman Charles Rangel has made it a priority to raise the cap gains rate to ordinary income level. That is just not even debatable. Democrats have three main objectives in tax policy, namely reduce the bite of the AMT on middle class taxpayers (which republicans also support), raise cap gains rate to ordinary income levels and raise marginal rates to Clinton-era levels or above. They have made a big show of attacking the indefensible hedge fund "carried interest" tax dodge, but nothing has come of it, since hedge fund managers have paid a lot of protection money to the democrats. They also want to reinstate punitive death tax rates and remove the tax break for dividends, among other proposals.
If you think taxes are too low, vote Democrat.
