Politics in the social medias

What about politics? Is it ok to use social media to promote certain political ideas? 

It is a good idea to use social media etc. for politics, as long as you're not just using it to say rude things or tell lies about other political parties.
It is an easy way to get your word out, and promote your political beliefs. If people are really into politics, it's a nice way to get to know politicians opinions on different subjects, by following them on fx twitter or facebook.

For instance, Mitt Romney writes rude things about Obama under the election.
