what does the committee do?
Do they evaluate and endorse candidates?
yes
Committees are just a platform - they are as good and active as the members that join and participate. Yes, support for candidates, signature drives, outreach on principles - Constitutionally limited government, individual freedom, education, contingent in the local schools, finding/helping candidates. Having no problem rejecting rinos. Providing a place for the like-minded to gather and communicate in a sea, at least in my case, of lieberalism.
