The power of incumbancy

John Baer has an editorial in the Daily News about the Santorum-Casey matchup for Senate, and cautions against reading too much into the polls showing Santorum weakening. He points out the vast resources available to incumbents, not only of finances but of in-kind services and the hesitancy of voters to pass up a representative with leadership clout for a freshman replacement. All good points to keep in mind as we get closer to reality space in this campaign.
