A summary of the recent polls, which are quite consistent with each other, shows Obama with a solid first place position in South Carolina, followed by Clinton who in turn has a solid lead over Edwards. The Democratic South Carolina primary is this Saturday and is the last vote that counts before Super Tuesday on February 5. Florida has its primary on January 29, but no delegates will be awarded and the candidates have pledged not to campaign there. All of the major candidates, however, will be on the ballot in Florida, something that wasn't true in Michigan.
A win in South Carolina could give momentum to Obama, who has been lagging in polls in a number of key Super Tuesday states like California and New York. The race might also finish off Edwards who needs a strong showing in South Carolina to be credible.
