There is an entire article on CNN.com about this, but I have to be honest I didn't read it. I just saw the chart.

MCCAIN OBAMA
Income Avg. tax bill Avg. tax bill
Over $2.9M -$577,148 +$699,872
$603K and up -$109,214 +$121,689
$227K-$603K -$15,877 +$942
$161K-$227K -$6,322 -$2,796
$112K-$161K -$3,736 -$2,135
$66K-$112K -$1,487 -$1,264
$38K-$66K -$608 -$1,118
$19K-$38K -$259 -$892
Under $19K -$65 -$567

Now the formatting is bad, but you can see that McCain lowers the taxes on everyone. Obama raises it MASSIVELY for the wealthy. But here is the thing...

McCain lowers taxes more than Obama on everyone making 66K or more. A household income of 66k. so two people making 30K a year.

If a work week has 40 hours, and there are 50 working weeks in a year. (allowing for 2 vacation weeks and holidays), that means there are 2000 hours. Divide 30K by 2000. SO basically if someone makes $15/hour or more, they are better off with McCain.

So, what exactly does Barack say he helps everyone under 250K? He does, but McCain does it better according to this chart.
