Voters think Obama's the Ronald Reagan tax-cutter of the 2008 election

So the facts of a middle-class tax cut are far different from what Obama claims. Obama also says his tax rates will be below those of Ronald Reagan. Wrong. Obama will raise the top rate to 39.6 percent, whereas Reagan left taxpayers with only two brackets of 15 and 28 percent.

Incidentally, the income cap for Social Security and Medicare taxes was about $42,000 when Reagan left office, compared with $104,000 today and the threat that Obama will raise that cap significantly.

It’s also worth noting that the Reagan tax-reform bill of 1986 mistakenly allowed the capital-gains tax rate to move up to 28 percent from 20 percent. Many believe this was a significant factor in the stock market crash of 1987.

Similarly, Obama intends to raise the cap-gains tax rate from 15 to at least 20 percent. It’s a risky move. Of course, Obama says only rich people will pay the higher cap-gains rate. But the reality is that a cap-gains tax hike will raise the after-tax cost of all capital, which will depress the future value of all equity assets.

McCain has recently proposed a reduction in the capital-gains tax rate from 15 to 7.5 percent. With 100 million-plus investors out there, and nearly two of every three votes in national elections being made by shareholders, this is right on target. Last Friday, McCain told me in an interview that a “low capital-gains tax is probably the greatest incentive for investment that we have in America today.”

In the frenetic final hours of the campaign McCain is also talking up his corporate tax cut, which would be a tremendous boost to plunging stock prices since corporate profits are the mother’s milk of stocks. Indeed, McCain’s overall tax-cut plan is far more powerful than Obama’s when it comes to creating jobs and stimulating economic growth. But his marketing effort appears to be too little, too late.

These things do, however, have a way of balancing out: If Obama and the Democrats go on a tax-hiking spree to penalize successful earners and investors, they will pay for it dearly in 2010 and beyond.
