As much as I hate to admit it, Scott Walker has had a pretty decent start to his presidential campaign. He did well in wooing voters in Iowa and won a silly online poll at the Drudge Report.

But as much as Walker thinks he is king of the world right now, David Catanese wonders if Walker is setting himself up for failure.

Catanese points out three areas where Walker could trip himself up. He says that if Walker doesn't win in Iowa's caucus, people will wonder what happened to him.

Catanese also points out that Walker will be targeted from all sides and that he is rather vulnerable, as he demonstrated last Sunday when he couldn't find anything big and bold to do in Syria.

Thirdly, Catanese wonders how long Walker can keep his song and dance going, trying to appease his red-meat teahadist base and the big money, establishment donors.

As Catanese points out, Walker has to keep up his charade of being a viable candidate for a long, long time:

The problem is that he's risen so early, there's ample time to pick him apart from every angle.

This isn't the Rick Santorum surge a week ahead of the Iowa caucuses. There's a whole year left on the calendar and Walker just might've earned himself several beat reporters solely dedicated to him. If he begins to stumble, the chattering class will wonder: Did he peak too soon?

Walker's situation is not unlike one of a decent college football team that jumped to a surprising, early lead against a top-ranked opponent.

With nothing to lose, the team rolled big early, and its aggressiveness was duly rewarded.

But that top-ranked opponent always makes a move for a comeback in the second half.

There's too much time on the clock left to try to just run it out against such a wide array of talent. Walker's going to need to play top-seed ball for 12 months.

I would also point out that Walker has a tendency to overreach himself and get a bit too cocky. This could present Walker with problems, including the backlash he is getting from going after all levels of education.

And if - more likely when - Walker and company makes Wisconsin the latest victim of plantation economics (otherwise known as Right To Work), the protests he will have to deal with will make the ones four years ago look like a stroll in the park.

Two years is a long time for Walker to try to keep all the plates spinning and keep all of the smoke and mirrors up at the same time.
