It goes by many names: loot, lucre, dough, greenbacks, clams, moolah and cash.
Whatever name it goes by, it's hard to get elected, even to local office, without at least some of it. But a candidate needn't spend too much to make a good showing, experts say.
Candidates interact with money in two main ways on the campaign trail - getting it and spending it.
The getting, says Joe Capowski, former mayor pro tem, is just a matter of sending letters asking for funding from "400 of your closest friends."
Of course, sending those letters out generally requires some sort of seed money, which often comes from the candidate's own pockets - albeit somewhat indirectly.
A candidate often loans a little money to him or herself, then pays that money back once the donations start rolling in.
These contributions range from the small - council candidate Will Raymond netted $10 from Tom Jensen, leader of Students for a Progressive Chapel Hill - to the enormous. Paul Newton, running for Hillsborough Town Board of Commissioners, received $3,500 from one contributor.
Chapel Hill has a mandatory cap on donations from individuals of $200, and many accept no more than $100 from any given person.
The spending of the money falls neatly in one sector: advertising.
