“giving my money directly to candidates I support and ignoring the party”.
This is what I do now too, Gonzo. If the RNC supports Rinos, which they currently do, they will not get one plug nickel from me.
Research the core Conservative candidates around the country who have a chance of winning in key races...and contribute what we can to help them.
Only problem with this is that you get on their mailing lists for life! :-)
