To build on a few of Blackfin's observations, based on what I'm reading from reader comments to our wonderful blog here, the following:
Heidi worked for the Chamber of Commerce (and is therefore a sellout). Heidi worked for the Chamber and got fired (and is therefore not a sellout).
Charlie is going to liberate Athens from the tyranny of the intown neighborhood "treesex" freaks. Heidi is going to liberate Athens from the tyranny of developers and other anal-retentives.
Charlie is a goof and a puppet of the Chamber with few ideas of his own. Heidi is the anti-christ, beholden to intown granolas and other communists who look longingly towards May Day.
Charlie is pro-smoking. Heidi is pro-smoking. No wait, both are against smoking. No, wait, they are for it, before they voted against it.
Benefits Good, Benefits Bad. Benefits Gay? Benefits Rad.
