Not whining like a kid and not supporting something just because it doesn't look like it's gonna have a landslide win or even may have a chance to lose.
It is a closed voting system still, ffs. Nobody will judge you because you take some minutes and stand by something you support even if you think it is going to lose, which is still just a propaganda effect as the French 2nd election just showed how people are more prone to get their asses political for a few days and go vote for what they want.
