Sounds like a very viable position, if it means "Don't send money to the RNC, send it to the most conservative individual candidates in whatever jurisdiction".
If the tactic is adopted by most Republicans, it will help conservatives, starve RINOs of funds, and perhaps produce a change in the RNC leadership
I almost agree, except for the "change in leadership". If the RNC leadership finds that there is NOTHING they can do to get conservatives to send them money, they will be forced to appeal to other people who WILL send them money, and that will be the RINOs. So the RNC will end up more liberal than ever.
The only way to get the RNC to cater to conservatives is to give them a carrot, to suggest and show that if they are reasonably attuned to conservative needs they can get money from us.
