I think the separation between HN and politics is intentional. In fact, not too long ago they strictly banned any political submissions for a week (although they cancelled it early because nobody could agree on the definition of political). I think your best bet in the short term is to create a custom subreddit, invite a bunch of people from HN, and see how that goes. Since you have the early momentum from the audience you want you can set up the mods early and set the tone for the future. Later on you can create your own website if reddit becomes problematic.
