Yes Genius, it's a coincidence. Tell that to the residents of Texas and the other six states that have no state income tax. Members of congress from those six states have been fighting to get this passed for some years now.
Congress is trying to legislate morality and govern human behavior with the tax code. It has been so for quite a while. Get your facts straight.
Besides, if you had ever looked at Bush's tax return, which is public for all to see, you would understand, as I do, that 1) HE doesn't make changes to the tax code, and 2) He hasn't really taken advantage of the benefits available, much less any "new" benefits. He pays far more taxes on far less income than Kerry or his wife ever did.
Check out Kerry's tax return. It's a whole different story there.
