Get someone to vote for you in exchange for something

Most commonly you get them to vote for you in exchange for you voting for them 

Vote for people who align or are at least somewhat agreeable with your policies

The hope is that once you and they are in government you'll collectively be able to work towards your policies

Vote for people who have different policies that you can at least tolerate to prevent the people with scary policies from taking over

Get someone to vote for you in exchange for something

Then renege on providing that something

Most commonly you get them to vote for you in exchange for you voting for them, then simply don't vote for them or pretend to vote for them before you switch your vote

Suddenly vote or change your votes RIGHT before election results are tallied

Do this on the first day of the month at 11:50 PST for optimal chaos

Highly risky

You'll want to get a Parliament that is extremely unpopular elected with a low turnout in the election

Then on the next election preemptively vote for your party/policy/group but make sure you don't get anyone else to vote yet

Then purposely vote for a Emergency Count and get other people to support it (but not vote on parties/policies/ groups)

Get more people to vote for you

Do this by promising policies or being personable

Alternatively do this by using the fear of someone else getting elected

Or you could threaten people to make them vote for you

Or you could just tell them to vote for you, some of them will out of a desire to appease

Distract people with nonsense so that they forget or aren't made aware of voting

Pick the same policy/group as a existing party and feed off of their success

Challenge the party with the same policy/group as your party to a duel

Whoever gets more votes during the duel challenge gets to keep the policy (in the server rules)

Then use another tactic to get more votes than them

It might be worth getting one party to change their policy/group to not overlap with another party's policy/group so that you can target only one party

It might be worth getting two parties to merge so that they can't be individually targeted and don't have to constantly vote trade by voting for each other

This involves voting for people in such a way that votes are divided evenly and the Parliament can't get anything done

You'll want to vote for every candidate except the candidates already getting votes
