Romney may be able to reverse some of the damage Obama has caused, but he won't be able to reverse all of it. Without Republican control of the senate, Romney won't be able to repeal Obamacare. A socialized healthcare system is probably enough to insure our continued downward spiral into a permanent social welfare state with a never ending recession and huge deficits.
If the captain of the Titanic had been replaced with a new captain, right after hitting the iceberg, he would be captain Romney.

Charles Krauthammer is an amazing person. He's been a quadriplegic since his first year at Harvard Medical School. He went on to become a medical doctor and is a board certified psychiatrist as well as a Pulitzer prize winning journalist.
