Without question, the Barack Obama infomercial served as a very slick and powerful recitation of the biggest promises he's made as a presidential candidate. But the very bigness of his ideas is the problem: he seems blind to the concept his numbers don't add up.
They list five different facts showing that Obama cannot keep his promises to his supporters or the American people and they end by making the following point:
If he closes every loophole as promised, saves every dime from Iraq, raises taxes on the rich and trims the federal budget as he's promised to do "line by line," he still doesn't pay for his list. If he's elected, the first fact hitting his desk will be the figure projecting how much less of a budget he has to work with - thanks to the recession. He gave us a very compelling vision with his ad buy tonight. What he did not give us was any hint of the cold reality he's facing or a sense of how he might prioritize his promises if voters trust him with the White House.
Go read the whole thing, the reality that Obama supporters close their eyes and ignore, because they cannot dispute it, is the basic simple fact that 2 + 2 equals 4, except in ObamaWorld.
