Factcheck goes over Bush's "Kerry will raise taxes by $900 billion" claim.
They can't conclude whether it's true or not because basically Kerry hasn't given enough details of his plans. Looking at his website, the only tax increases I see are rolling back on $200k earners, some capital gains, a different prescription plan, and I've seen him mention estate taxes elsewhere. His site also says a little about cutting spending.
Besides his health care plan, he is also promising various tax credits, state tax relief, and cutting the deficit in half. If the numbers can add up to accomplish all that (I don't if they can, can they?), he needs to show his calculations. If there's going to be a debate every month, he should have answers ready.
Unless he does give more details, this is just like Bush's dishonest economic forecasts. I always liked Dean for criticising the other candidates for childishly promising the world without raising taxes. I notice Kerry's dbunker item on the Bush $900 billion claim, while it does clear up that he only wants to raise taxes on a small percentage of taxpayers, it still doesn't explain how those tax increases will cover all his programs. (speaking of the dbunker page, that debunking of the "voted 350 times to raise taxes" is very weak. They never say it's not true - is it true? If it is, they need to frame it some palatable context.)
