The Iowa caucuses results portend that the republicans just can't get behind any single candidate. That is good news for the democrats. If the republicans think that Rick Santorum can become president, they are pretty close to delusional. And Romney just can't get the whole party behind him. That leaves a lot of room for an incumbent president to maneuver - too much to stop him. (or her, which it eventually will be).
This is setting up for an Obama landslide, believe it or not. I happen to believe it. You might be landsliding me before it's over, but I'm pretty sure you won't.
