Investors' Business Daily makes the case here.

But as Iraq fades as an issue due to its success, the economy once again looms large due to its uncertainty. On that issue, and many others, suspicions linger that McCain is running in the wrong party and merely a GOP clone of Joe Lieberman.
Consider Michigan, home of the beleaguered American auto industry. McCain, together with Democrat John Kerry, were initial co-sponsors of the 35-mpg Corporate Average Fuel Economy mandate that just passed Congress. Estimates are that it will cost the domestic auto industry $85 billion over a decade and imperil thousands of jobs.
McCain's campaign says he has never voted to increase taxes. Yet General Motors Vice Chairman Bob Lutz says the bill will add an average of $6,000 to the price of a new car, in effect a 21.4% tax hike on current average car prices.
It gets worse. McCain supports an energy tax in the form of a bill co-sponsored with Joe Lieberman that would cap the amount of carbon dioxide that energy-producing companies could emit. It is essentially an energy-rationing scheme not unlike Bill Clinton's infamous BTU tax.
Companies wishing to increase energy production above the cap would have to purchase unused emission credits from other companies. In a letter to McCain in July 2007, the EPA estimated that the "tax" would amount to 26 cents per gallon by 2010 and 68 cents by 2050. The EPA says the McCain energy tax would increase electric bills by 22% in 2030. This is hardly the way to avoid a recession.
It gets worse. In April 2002, McCain joined John Edwards and Hillary Clinton in defeating a measure to open an area the size of Washington-Dulles Airport in the frozen tundra of ANWR to energy production.
He has voted against drilling in the Arctic National Wildlife Refuge no fewer than four times. In expressing his opposition, McCain equated ANWR with the Grand Canyon, a national monument. But as we have said repeatedly, the drilling area is in fact what hell would look like if it froze over.
Aside from supporting higher taxes and energy dependence, McCain shares the disdain of Democrats for America's pharmaceutical industry. Never mind the miracles it has produced.
In ABC's New Hampshire debate. McCain asked: "Why shouldn't we be able to re-import drugs from Canada?" He blamed high drug costs not on regulation and litigation, but on "the power of the pharmaceutical companies." When Mitt Romney argued that they weren't "the big bad guys," McCain replied, "Well, they are."
McCain has joined forces with Ted Kennedy to support amnesty for illegal aliens and with Russ Feingold to restrict political speech. He also backed the Sarbanes-Oxley monstrosity that makes American business less productive and competitive.
