Phil Jennerjahn is well organized. He works his campaign downtown as well as on the Westside and makes all the candidate fora. He is about to tap the resources of John McCain's former westside operation, a move that will bring him fifty people to work on the ground.
David Hernandez won't be stumped on any single issue that might come his way. He's fought for various causes in Sacto and in the LAUSD board room.
Zuma Dogg enjoys a widespread fan base who are surprised to find out when he starts rapping issues that they sound like legitimate concerns of the City's vast politically disenfranchised population.
Walter Moore has bumper stickers. Craig X. Rubin has charisma. Carlos Alvarez has street cred with the No on 8 movement.
While none of the Mayor's challengers are threatening to take 50% of the vote invididually, in aggregate they might, especially in the event of a low turnout (estimates on the high end are 20%). Which would force a runoff between the Mayor and the second place vote-getter; a potentially embarrassing situation for an incumbent who has worked hardest in his campaign at convincing media that he has "no opposition."
Media have largely complied, but that appears to be changing, and micromedia is more than happy to help the candidates get their messages out. Today CityWatch puts up video of a recent candidate debate. There will be another one Sunday, sponsored by the political blog MayorSam, and Moore, a target of many of the challengers, has agreed to attend. (The Times board, conversely, didn't even interview all the challengers in person.) But with two weeks to go, the challengers are finding ways to find voters.
