text: We have primaries. The presidential primary system is the generally the same as in other states. I should also note that we have closed primaries -only registered Democrats can vote in the Democratic primary and only registered Republicans can vote in the Republican primary. In some states unaffiliated voters can choose one primary to vote in, but unaffiliateds are not permitted to vote in primaries in Connecticut.  The Presidential Primary is usually on "Super Tuesday" - the Tuesday in early March when the most states simultaneously hold their primaries.
