If she's created a network of precinct, county and other GOP leaders, then that's huge. In which case, she has a very good chance to win Iowa if she jumps in, since it's all about organization and GOTV there. A win in Iowa, and I would suspect S. Carolina, would propel her into Super Tuesday with some good momentum.
Like I said earlier, I'm not 100% convinced she's going to run, but if she does, this is going to give her a leg up on everyone and makes it a Romney vs. Palin race (no one else matters at that point except as a drag on them, imho).
No, read it again carefully. "...even if it’s not being officially coordinated by her or her advisors...".
