Obama has pledged to cut taxes for 95 percent of American families. Yet the media don't seem to challenge him as they challenged the Bush 41 -- who simply said he wouldn't raise taxes, not that he could cut them despite a large deficit.
It could be that the press have seen that tax cuts can work, and lead to revenue increases. But I think a larger factor is a change in the media. We expect politicians to pander, not lead. Like the public, we no longer demand that they make difficult choices.
