A Poll Sure to Shake Up the Psychology of the Race If Nothing Else: ABC/Washington Post Poll Has Obama Ahead in Iowa

    A new ABC/Washington Post poll has Obama ahead for the first time in Iowa since a Newsweek poll showed him with a similar lead in September.
    The results for the top three:

     Obama 30%
     Clinton 26%
``  Edwards 22%

    The main import of the poll -- besides giving a psychological boost to the Obama campaign -- is to deliver a blow to Edwards. If it looks like he can't compete with the top two, will he lose further support?
    Rasmussen is in the field polling Iowa right now. That poll is sure to receive a lot of attention in the next few days to see if this is some kind of aberration or represents a trend. And, just to put a little spin on it, the last ABC/Washington Post Iowa poll at the end of July had Obama ahead by 1%, at a time when other pollsters had Clinton way in front of Obama in the Hawkeye state. So, we'll see.
