In a recent Wall Street Journal op-ed, former Bush advisor Karl Rove wrote: “Taxes still matter because they are highly visible and unpopular. In a July 2008 Pew Poll, 52% of Americans said it was ‘difficult to afford’ taxes. And in times of economic challenge, concern about taxes rises—especially among blue-collar households skeptical of promises that that tax increases won’t affect them.” Mr. Rove concludes: “The tax issue has lost its political punch in the eyes of some commentators, but not among voters.”

Apparently, not many among Democrat politicians either. Recently, Senator Bernie Sanders, Independent from Vermont and an avowed socialist, proposed an amendment to the Paulson financial rescue plan calling for a 10 percent surtax on wealthy individuals earning more than $500,000 annually to help finance the cost of the plan. Interestingly, the amendment was defeated on a “voice vote” because Democratic Senators feared going on the record in favor of higher taxes only weeks before an election.

Clearly, Democrats remain politically vulnerable on taxes. During the recent Vice Presidential debate, Alaska Governor Sarah Palin relentlessly attacked Mr. Biden and Mr. Obama for proposing higher taxes:

“Now, Barack Obama and Senator Biden also voted for the largest tax increases in U.S. history. Barack had 94 opportunities to side on the people's side and reduce taxes and 94 times he voted to increase taxes or not support a tax reduction, 94 times. Now, that's not what we need to create jobs and really bolster and heat up our economy. We do need the private sector to be able to keep more of what we earn and produce. Government is going to have to learn to be more efficient and live with less if that's what it takes to reign in the government growth that we've seen today. But we do need tax relief and Barack Obama even supported increasing taxes as late as last year for those families making only $42,000 a year. That's a lot of middle-income average American families to increase taxes on them. I think that is the way to kill jobs and to continue to harm our economy.”

Senator McCain needs to pick up where his running mate left off by repeatedly explaining his pro-growth tax cuts, and relentlessly pounding Barack Obama for wanting to raise taxes, from now until Election Day.
