McCain can call Obama a socialist or Teddy Roosevelt his hero, but not both  

In order to get the same amount of revenue with a flat tax as we do now, the middle class would have to have its taxes raised a LOT, crippling them. Remember, every dollar makes a lot more of a difference to someone making $42k (iirc, that's the average income in the US) than it does to someone making a few hundred thousand a year.

So in that way, a flat tax WOULDN'T be fairer, because it would reduce the burden on the wealthy at the cost of dramatically increasing it on everyone else.

The "Fairness Doctrine" has nothing to do with taxes. "The Fairness Doctrine was a policy of the U.S. Federal Communications Commission (FCC) that required the holders of broadcast licenses to present controversial issues of public importance and to do so in a manner that was honest, equitable, and balanced." - http://en.wikipedia.org/wiki/Fairness_Doctrine

I do agree that a flat tax on everyone's income - no deductions, no exemptions, no loopholes - is the best way to go.

Fairness, and right are two different things. A flat tax would take the same percentage of tax from everyone, everyone is equal. If you have ten apples, the goverment takes one, if I have a hundred the goverment takes 10. That is fair and right.
Fair or right has nothing to do with making people that make more, pay a higher percentage of what they make just because they made more. I don't understand why people can not understand when it comes to taxes why we can not treat everyone the same. Espically when they want equality eveywhere else.
The goverment is not suppose to be the safety net for every citizen. People should be responible for themselves. Again, if you as a free person want to give money to someone due to their situation that fine, but why should I have to give money or support to someone who is where they are due to choices they made and have taken so much from family and friends that they will no longer support them. The goverment is too big and needs to live with-in its means, just as I do.
In a free society I can give to whom I choose, or not. When the goverment or someone else makes that decision it is not freedom.

"One can admire a particular person and look at them as their hero without agreeing or believing 100% in their beliefs or political views."

And yet, Obama couldn't have even served on the same board with Ayers without being called a terrorist sympathizer (or even an actual terrorist) by conservatives.

Double standard, anyone?

If it were merely one board, and speeches it would not be that big of a deal. But to initially say you were't friends, then hold your coming out political party at his house on your block, and say that Ayers did not host it some other female did, then she comes forward and says no I did not host it, Ayers did. It appears that he is lying, deceptive, not being 100% truthful. I know everyone lies, but we are talking about Obama at this time. Lawyers and politicians use words to circumvent truth, after all,"What is, is".
We, as human beings tend to associate in our personal lives with people that hold the same values and interests as ourselves. Look at who Obama hangs with, and look at their values, interests, and morals and you will see a reflection of Obama's true beliefs.

Since Theodore Roosevelt died some 17 years before McCain was born, it is highly unlikely that they associated in any way! Admiring a famous President from our past is far from the same thing as having "real-life" associations with questionable people!
