The folks at Factcheck.org have found flaws in new McCain and Obama spots.
Obama released a TV spot saying McCain's campaign got $2 million from "Big Oil" while McCain proposed "another $4 billion in tax breaks" for the industry.
The truth is that McCain's campaign has received $1.33 million from individuals employed in the oil and gas industry, not $2 million. Obama himself has received nearly $400,000, according to the most authoritative figures available. We find the $2 million figure is based on a mistaken calculation.
Furthermore, McCain is not proposing new tax breaks specifically targeted to the oil industry. He's proposing a general reduction in the corporate income tax rate, which Democrats figure would benefit the five largest oil and gas companies by $3.8 billion.
A new McCain ad calls Obama a celebrity (true) who says he'll raise taxes on electricity (false).
McCain's new ad claims that Obama "says he'll raise taxes on electricity." That's false. Obama says no such thing.
McCain relies on a single quote from Obama who once - and only once so far as we can find - suggested taxing "dirty energy," including coal and natural gas. That was in response to a reporter's suggestion that a tax on wind power could fund education. Obama isn't proposing any new tax on electricity or "dirty energy" as part of his platform, and he never has.
It's true that a coal/gas tax would raise electric rates, but so would a cap-and-trade program to restrict carbon emissions. Cap-and-trade is an idea that both McCain and Obama support, in different forms. Neither candidate characterizes cap-and-trade as a "tax."
