If you lack the initiative to figure that out, you may not be what /we/ need.
But because you seem to be in pain and I have white empathy, I'll make a few suggestions:
1) Look into your county's grand jury. This is a regularly overlooked part of local politics that is surprisingly influential. You can push your nose into law enforcement, zoning laws, how many niggers your county will ship to the nice neighborhoods, etc. The appointment system is as crooked as Tammany Hall, so keep your nose clean and don't reveal your power level. The superior court will look over your social media history before letting you join.
2) School board. This is a regular Harper Valley PTA for backbiting and petty grudges, but depending on your state you can influence textbooks and curriculum. Try to get teachers armed and keep mudbloods out of the good schools. It's also good for strategic gossip.
3) Local party committees. If you're good at schmoozing pro tip: you aren't you can infiltrate your local Pepsicrat or Cocacolan party machine. It doesn't matter which one, you'll be climbing a ladder with Jews on top either way. I suggest doing honest work for the Republicans, but sabotage the Democrats if you choose them.
4) City council speaks for itself, as does the county board of supervisors.
5) State legislature. States vary in their requirements here, and it's way easier to get elected in some states New Hampshire than others anyplace else. Worth looking into. Your job there will be to raise money for a political party without accidentally calling the governor a kike. Do a good job of both, and you might be on your way to Congress.
Avoid
Don't bother with/stay the fuck away from these pitfalls of politics:
1) Starting your own party or movement. This will never work. Many men, most far greater than (you), have tried this and failed. Maybe the best man to fail the worst was Rockwell himself. The fucking madman went full 1488 on American politics and then got shot by a Jew who took his gig.
2) Joining an established "fringe" group. The day you sign the militia membership application, or whatever the fuck pagan thing they have you do, your name is on the list. Avoid. If you're under deep-cover, extra points for denouncing your local FBI dating service militia as antisemitic.
3) Lone wolfery. It may be fun to see them run and scream, user, but it only hurts us InB4 Muh PR. No shootings unless you can either make a really good case for self-defense, or you're ready to walk the short-but-glorious path of the dead warrior. Use your head like a white man, not your fists like a nigger.
There, you faggot. Name a post office after me when you're in charge.
