The IRS is not obligated to recognize Gay Marriage even in States that have legalized it. The Feds write Federal Tax Laws to suit their own desires, and that desire is all about $$$

You are attempting to apply "logic" to the Federal Bureaucracy. What the hell were you thinkin'???
You're hitting on all 8 cylinders

I'll see your Heinie and raise you a Becks Dark

Wait a minute...That came out wrong somehow

If your real good I'll even go for a Laphroaig Single Malt...
Plan "A" (as announced by the current leadership) is to dump the existing tax cuts by allowing them to expire, which nails everyone from the top to the bottom. Especially the middle and bottom. That way they can say they didn't raise anyones taxes, Bush did, because it was BUSH's tax cuts that ran out
Next come "targeted" tax cuts for Middle & Lower Income workers. The targeted cuts currently proposed are less than the Bush cuts that are set to expire as things stand now. It will still be Bush's fault.

(That Bastard had it planned this way all along to make Obama look bad) He was such an evil genius
The upper-middle and upper class will see a targeted increase to offset the lost revenue. Everyone will see a tax increase for medical care if the health ins. legislation goes through as proposed, with every one in the higher income brackets getting an extra tax surcharge because they are evil and the bane of human existence.
Then of course comes the "Carbon Credit" taxes, which will raise ordinary utility costs for the average family a few $K per year.
Oh and don't forget that the IRS will be in charge of making sure we all have "federally approved" medical insurance under the current health care proposals (unless you are a union member), and if you do not you will be assessed an annual penalty of anywhere from $700 to several $K depending on how much you earn.
This of course will be bad for the job market, and once again Obama has renewed his pledge to push hard for targeted tax cuts for small business in the form of making them exempt from "Capital Gains Taxes" in order to offset any burden they might endure and stimulate job creation in the private sector.
There is of course one small problem with that particular bit of sophistry from El Hefe Grande' (a little "racist" lingo for Bob

). Small business do not pay Capital Gains Taxes. Homeowners who sell their homes do. Retirees who are living on stock investment income do. They of course do not get the exemption.
"Capital Gains Tax Exemptions" for Small Business is the functional equivalent of providing guaranteed maternity care insurance for 75 year old gay Men
The small businesses pay ordinary Income Taxes, which are slated to go back up to 41%... before adding in the Carbon, Insurance, and other penalties waiting in the wings.
