Seek a realistic seat first and foremost. State rep or even something smaller. Then move onto bigger targets once you're more experienced. Learn how the game is played, learn to talk to voters and fellow politicians once in office. That's my best advice to you. Outsiders do come in and take the world by storm but they're usually "in the game" for much of their life (such as Trump being a big donor or Rand Paul being son of a Congressman).
