The caucus idea is very interesting.
For one thing, in so many townships, the local conservatives need tutorials on RRO (ROBERTS RULES OF ORDER) to defend themselves knowledgably against the entrenched precinct & county leaders who in some cases are quite liberal and unfriendly to TEA PARTY concerns, experienced in shutting newcomers down, but doing so by the book.
A caucus could educate those who would resist the Leftward movement of the Rep. Party who need the skills.
If conservatives are not strong enough or unified enough to win the GOP nomination, what makes anyone think we would be strong enough or unified enough to win a general election in an unknown third (or fourth) party?
The RINOs will support a conservative if they have to. So why not use them, like they have used us?
