General Elections

That would put me as Senator of 3 hubs. Is that a good thing?

Probably doesn't matter much if you are senator several places, even main hubs. Especially if you are not president too. Its not like Senators have much power.
As long as senators don't change system name and are available to be contacted to approve gates, they are doing a good job. Not much else they can do really.

My main colony will not be allowed to vote for president, to avoid unfair election, they just have too many votes(75 million extra votes from palaces).

Jam said he was willing to trigger a general election. I suggested it might be a good idea to do a mass mailing about it. Might encourage a few to become active again. Waiting to hear back.
