In August 2010, the Democratic National Committee and the Republican National Committee adopted rules prohibiting states, other than Iowa, New Hampshire, South Carolina, or Nevada from holding a presidential primary before the first Tuesday in March in the year in which a national convention is held (Democratic National Committee, Delegate Selection Rules, Rule 11(A) and Republican National Committee Rules, Rule No. 16(c)(1)). In response, Connecticut delayed the date of its presidential primary from the first Tuesday in February to the last Tuesday in April (CGS § 9-464).
Before Connecticut has its 2016 presidential primary, several other states will hold theirs, including 13 on Super Tuesday (i.e., March 1). Curious about exactly where Connecticut falls in the lineup? Take a look at The Council of State Governments’ timeline of every state’s primary or caucus.
