Kerry.
Let's say I have a monthly income of $10,000 and spend $10,000 per month. Then I go and get 10 credit cards. If I rack them up paying for a war, what am I going to do when the next bill comes? If I follow Bush's lead, I'd lower my income to $8,000.
When the crunch comes, it's gonna be ugly. Yes, tax revenues will increase as the economy fires up, but just enough to close the deficit, NOT enough to pay for this war, eliminate the deficit, and pay off the national debt. I'm just a pilot, so you know this has occurred to Bush and his advisors, but they still paint Kerry as a tax hawk, as if taxes are only meant to punish hard working families. Taxes are a necessary evil, especially when you need to pay for a war (justified or not).
As for the baby killing arguement: If Kerry supports crushing babies skulls, then Bush supports sending teen-agers to get their guts plastered all over some dusty street in a foreign country. Spin doesn't do anybody any good. Abortion and war are serious, complex issues, and reducing them to rhetoric is irresponsible.
