The town squares and all the commercial property around them are owned and managed by the Central Development District (CDD), which is owned by The Villages, which is owned by the Morse family. While the choice of speakers permitted within The Villages may be objectionable to some, it's hard to argue that the guy that owns things doesn't have the right to invite who he wishes to appear and speak on his private property.

There may be some interesting legal questions about other parts of The Villages though. While the big rec centers are owned by the CDD and managed by the Recreation Department, which is part of TV organizational structure, both organizations must now take a significant amount of direction from an elected board of residents. It seems to me that if a majority of that board wishes to have equal representation from the political parties or candidates for office, they could direct the CCD and the Rec Department to make sure that happens.

But you might ask, given the makeup of The Villages, what chance might there be that the board managing the rec facilities would direct the developer to have just as many Democratic or liberal speakers or events as Republican speakers or gatherings? The answer is pretty self-evident, isn't it?
