The chairman is the head or the presiding officer of any political party
who can also influence the selection of candidates of the party. He is responsible for the fundraising of the party and running the political campaigns, and keeping the public relations.

Republican state chairman becomes a member of his party's national committee:

1. If most of the representatives in Congress from states from which it has been elected are republican.
2. If the states of Congress have a Republican governor.
3. His state has cast the electoral votes in the last election for the republican candidate.
