Have you looked at all 53 ballot-qualified political parties in the US and decided that none of them meet your needs? It'd be far easier to work with one that already has most of the basic work done that taking an NIH approach and building up a new one from scratch.
You jump almost immediately into fundraising after stating exactly one vaguely defined plank ("fuck the rich!"), which makes me a tad suspicious about your motives. No offense. Note Occupy Wall Street was essentially "fuck the rich," and they're more or less still around - again, working with people who've already started down this path is going to save a lot of work and probably be more successful than trying to start a party in Lemmy.
