Who you work with certainly matters, but it does show that it's incredibly easy to get a foot in the door with a lot of political things.

People complain so much about politics as being this completely foreign and detached thing. But it's not if you put a bit of effort into it.

Well yeah of course it's not hard to get involved in politics, if the involvement is supporting people who are rich and powerful even if it is via the use of a more modest looking young mouthpiece. OP was supporting a conservative party, so basically going with the flow of a bunch of what a bunch of influential and rich people wanted as their pawn. If you have something that is of little consequence to the rich, like mothers against drunk driving or something, sure you can probably get it done as it's a token gesture and the powerful just pull strings to get out of those prosecution anyways.

If you look at actually trying to move the meter away from the status quo of the rich and powerful, rather than just repainting the pieces on the chess board, you see politicians like Bernie Sanders or Ron Paul found the whole thing rigged against them. Bernie was railroaded by the upper echelons of his own party and Ron Paul found his name magically erased from practically all the talks on the high level debates in the press to the point they would just skip over his name in the primary poll rankings.
