1) Romney's campaign message is essentially positive; Obama's is overwhelmingly negative. People always prefer promises of something better, but Americans are especially hungry now because times are very tough. Romney is offering concrete and realistic plans to help America grow again and create millions of new jobs. Romney's message and agenda appeal to all Americans, not just certain groups, and tell them they are not imprisoned in their current economic "station" as Obama would have them believe. Though Obama's promises of "hope and change" in 2008 were vague, at least he presented them as something positive. Today he tells us we must accept an America in decline both internationally and domestically. He insists that 8 percent unemployment is the new normal and that we must adjust to the malaise because it is going to take a long time to make a dent in it.
2) Obama is appealing to people's baser instincts of envy, greed and fear and has deliberately fanned the flames of racial tension for political gain. This would have been bad enough if he'd not presented himself as a post-partisan, post-racial phenomenon.
3) Obama had the wind at his back in 2008 after happening on to a perfect financial storm he claimed he had nothing to do with creating. Today our financial outlook is actually much worse; we are much closer to a Greek-style collapse, and Obama has done nothing and proposed no ideas to avert it. It strains credulity to think Americans are gullible enough to swallow his shameless scapegoating of Republicans for problems he exacerbated and is unwilling or too incompetent to address.
4) Indeed, Obama's record has been horrendous in every category -- economic, debt, national security, military strength, energy dependence, social cohesiveness, religious liberty, race relations, health care and business. America is significantly worse off than it was when Obama took office. It will be extremely difficult for Obama to overcome the reality of his terrible record with his fictional whitewashing of that record.
