The other side may argue that Cebra is good, though. Again, nothing points toward Cebra coming off as rabid anti-Ron Paul or corrupt or even really evil. Plus, we don't know how he would function should he become the Chairman. If enough people actually do believe O'Connor can pull it off, not just on the basis of her being a Ron Paul supporter, but that she would function better than Cebra, then that should be what ultimately leads her to victory.
Here's something quite telling, though. This article about the election mentions Matt McDonald of Belfast, who said the following:

So there doesn't seem to be a good or bad here. It can be argued that O'Connor would probably be more approachable by Paul supporters, but that may be because they're more familiar with her than Cebra. I don't know the vibe over in Maine, so it looks like, without looking at any polling data myself, this could go either way.
