even cory booker, said no eat whatever you want. no need to panic about it. but it's an existential there. it's hard to square that. paul: some are proposing a carbon tax, not too many explicitly. that would be putting a price on carbon and raising the price of fossil fuels. some of our friends on the right, free market economists think that's the best way to go about it. everywhere it's been on the ballot, it's failed. >> it has failed. so you have to ask, how is it, as kyle described, most of these democrats have simply separated themselves from political reality as we know it. it's been very difficult to get a carbon tax through the congress and they just keep out-bidding one another on the subject of climate. paul: dan, look, these guys are running for president. elected office. they're political professionals. presumably they want to win. so why -- you said they he separated themselves from political reality. are they trying to lose?
