Who will take Washington state? Friday Trail Mix Rick Santorum and Mitt Romney may be battling over two delegates in Michigan, but this weekend, there's a much bigger prize at stake - Washington state's 43 delegates. Whose race is it to lose? We take a look in today's Trail Mix: The Washington state battle is a lot like the Maine caucuses - it's a two-step process. First caucus-goers participate in a presidential straw poll, and then they vote for county delegates. And that gives Ron Paul an opening. Paul's supporters have consistently been the best organized and motivated when it comes to mastering the obscure rules of the caucus process. Will they do so again on Saturday? We might now know until several months from now, when the county and state conventions happen. But keep your eye on reports Saturday night not just of the straw poll count, but also of whether Paul supporters are as organized as they've been in the past when it comes to the delegate race.
