The natives have peeked into the sausage tent and discovered how RINO nominees are made. A splash of varying state rules, a pinch of early timing, a squeeze of money, mix together, then change out part of rules. Let set. Add more timing and cover lightly. Let rise. Garnish with final rules . Serve hot, on a platform.
