There's a lot under the umbrella of "politics" that happens after you get elected. If you want to accomplish anything after you get elected (heck, even if it's just personal enrichment) you have to be somewhat skilled at getting others to work with you, one way or another. As a politician you can have flawless convictions and be right and well-informed about all your decisions, but at the end of the day you're just one vote (to use legislators as an example) and it does nothing if you can't convince or work with others.
