What are candidates in the 2008 American election to push their campaigns at local and state levels?

It really depends on what state you live in, and what part of the state. If the polls show a landslide for one candidate and that state doesn't have many delegates you rarely see the candidates other than a TV commercial here and there. The "battle ground" states are the ones that see all the action - Iowa, New Hampshire, South Carolina,....and the big states like California and New York, those states with mega amounts of delegates are the ones the candidates challenge.
