An early poll

Marco Rubio will have his work cut out for him - not particularly helped by having the State party apparatus endorsing Charlie Crist - if this early poll means anything. According to a poll of 300 Republican voters, conducted by Mason-Dixon Polling & Research for the Sachs firm, showed Rubio with only 18 percent of the vote, with Governor Crist at more than 50 percent of the vote (undecideds at 29 percent, and the margin of error being +-6).

While certainly Rubio would prefer to have done better, most political scientists agree that early polls are predictive of very little. And some of you might remember some also ran named Obama badly trailing Hilary Rodham Clinton in the early polls. What are early polls good for? Not quite "absolutely nothing." Politicians can use these early polls as part of their fundraising mechanism, which can in turn work on name ID, which can in turn improve future polls - which can be quite predictive of winners. But there is a lot of "noise" involved in this line of causation - making these early polls not particularly important.
