Here's something Sean Hannity said about this in 2009:
HANNITY: I have only bought American cars in my life, and GM is a sponsor and has been through a couple of years on my radio show. They made the turnaround in my eyes many years ago, and one of the problems is that I think government has played a role up until this point in terms of dictating what kind of cars we can buy.
Bad energy policy. We're not energy independent. I think number one, CAFE standards, mileage standards, safety standards. They've already had an impact on the economy. What are they going to do now? They're going to let the environmentalists design the cars?
Is that funny? Yes. Why is it funny? Because at the very time Hannity said all that, all that trashing he does of car economy and environmentalism, etc.,
he was not just hawking GM on his radio show, he was SPECIFICALLY hawking the VOLT, and touting everything about it he is trashing in the quote above.
And, good for him, he got paid handsomely in both cases.
