So, addressing:

Carratos- Any Senator who didn't vote to get rid of Force users would likely come under suspicion. Valid vote.

Relief aid to Chad- Really? Come on now. Voting for sending relief is a nice thing to do. Only a real dick would vote no.

Ban on Fornication- That one actually does have a valid vote concerning purity of race and, bringing into play the fact that an alien Senator voted for such a proposal could well have strengthened his position in the Senate amongst the other Imperial supporters.

Taungsday Observation- A small vote that made sense. See above reasons concerning showing support for Imperial voting.

Motion to Censure- Crion made an idiot of himself and ran his mouth. Enough said.

Investigating Vjun- Made sense, valid argument put forth by Lohden.

Non-human Voting Act- Domon was originally against. Once changes were made in the Act to improve it, he changed his vote.

Imperial Loyalist Committee- More kissing of Imperial arse.

Biological Weapons Act- Oh, sorry. Should have voted against that one. Wait, I didn't because it was a sensible act.

Balanced Budget Act- See above reason.

There have actually been a number of votes that Domon has either not taken part of or simply ignored. As such, you can hardly claim it is every single issue. If an act makes sense, is legit and has a chance of making Domon look good for supporting it, odds are he is going to vote for it.

Ryuun is a high supporter of Imperial thought as well, and tends to vote similarly. If you don't like it, as I said before, take it up with management. My point regarding the rules still stands.

1. Everyone wants to vote for the patriotic thing and not be seen as anti-Imperial, thus many Senators would just vote the same way because it was expected of them.
2. Many worlds have overlapping interests on may areas, depending on their history, government style, etc. So for example two governments who are monarchies should vote against anti monarchy bills, for example.

I believe in every case so long as a reasonable case can be made for a Senator voting in a particular way (backing another Senator fro example) then it is not unreasonable to act in this way. The rules allow for two senators, and there is an obvious conflict of interest always there between rules 1.2 and 4.1. Personally I feel so long as it does not get ridiculous (votes which are demonstrably highly against the interests or previous actions of a world) then there is no problem with this.

Equally, there is no rule preventing the creation of two Senators (everyone can do it), and so long as they are roleplayed, legislate and participate in debate (For example Oriel and Ordan both have similar agendas but have disagreed at times and propose legislation independently. Equally, Anaxes and Vjun are different worlds and have regularly been used in roleplay).

I do believe that it become a problem when a person (not to name names) shows no interest in developing roleplay or legislation around one character, and instead is happy to just vote in favour of their own legislation without ever participating constructively (or otherwise) in debate.

That said, enforcing such a "you must use a world to vote with it" rule would enforce a kind of "elitism" within roleplay where some sort of organisation would have to be formed and standards set for what you had to do to be able to vote. And frankly, even if these were put in place.. it does not take a genius to jump through hoops if they have the time for it.

Frankly, I don't think the situation is too problematic and reform isn't really needed.
