Expat interest in politics in Singapore

things are not that 'messy' compared to india, so during the election period, just do whatever you are doing like a normal day.

as expats, just concentrate on doing your job here well and maintain a good working attitude; that should be your primary focus and would be sufficient.

therefore expats do not have to worry too much about the politics here, unless something very earth-shattering regarding foreign workers has happened.

leave the politics to Singaporeans of course.

Foreigners are not allowed to participate in elections or even political movements in Singapore.
Not that it matters much, as Singapore "democracy" is best written in parenthesis due to the lack of choice.
But don't voice too loudly any discontent about the political status quo - this is unliked by those in power and will be dealt with harshly.
As Jonnielee wrote above: Leave the politics to Singaporeans (most of whom are also not interested in it, for good reasons)!

The world of politics is the same in every country where a zero sum game is played by the wealthy who win and the poor lose.
