Not McCain's best idea:
I was flabbergasted by John McCain’s proposal to suspend collection of the federal gas tax for this summer. Suspending this user tax would deprive the Highway Trust Fund of $8-10 billion in much-needed revenue to patch potholes, rebuild failing bridges, and keep the Interstates and other key arteries from further declines in their already pathetic levels of performance. And this comes at a time when the Trust Fund is already facing a 2009 shortfall of $2-3 billion (thanks to Congress legislating more highway spending than existing gas-tax revenues can support). Plus, since the gas tax is only about 5% of the cost of a gallon of gas, the savings to motorists would be trivial.
