A day before Tax Day, the deadline for filing taxes (or tax extension requests), the Senate voted 51-45 for the Paying a Fair Share Act of 2012—endorsing the bill that would make possible the “Buffett Rule” on taxes. But it fell short of the 60 votes needed to make it filibuster-proof. And the proposal failed to advance. “It is inexcusable that a multimillion-dollar earner can pay a lower tax rate than a Rhode Island truck driver,” said Sen. Sheldon Whitehouse, D-RI, after the vote. Whitehouse was a sponsor of the act, which would ensure that millionaires paid at least a 30 percent effective tax rate. Should he and other Democrats give up their drive? Or press ahead despite the odds?
