Obama and incrementalism

The L.A. Times has a pretty well reported piece about Obama's relationship to liberals. The kid's getting it from all sides at the moment. But what worries me, specifically, is this:

Advocates for stem cell research thought Obama would quickly sign an order to reverse former President Bush's restrictions on the science. Now they are fretting over Obama's statement that he wants to act in tandem with Congress, possibly causing a delay.

I'm sure one of my sharp commenters has an explanation for this. I don't have one. I'd love to see an executive order on this.

UPDATE: Link fixt.
