Lucan must be planning something impressive if he expects to get enough additional votes to accomplish anything noteworthy.
Kyle's goals and Lucans's cannot possibly align, and Ollidor's are diametrically opposed to Lucan's.
Maer will oppose him by default simply due to her stance on magic.
Anglatine is harder to pin down, but she's a fan of Danelle, so not likely to align too closely with Lucan.
Even if he gained all undecided/independent votes, Lucan won't be able to accomplish anything as the factions are currently arranged.
I think he might be aiming to just completely turn over the Monopoly board and seize power within the Faith, coup style. He probably thinks his mages and Angel give him the power and authority to accomplish it with relatively little opposition.
