SOURCE OF DATA: POLIDATA attempts to determine party control from district-by-district election results.
However, aside from the problems associated with this, party switching sometimes results in a change of
chamber control. See notes below.
MT State House, 2006: Election Results: 50 Dems, 49 GOP, 1 Other. After party switching: 49 Dems, 50 GOP, 1 Other.
GA State Senate, 2002: Election Results: 30 Dems, 26 GOP. After party switching: 26 Dems, 30 GOP.
DATA PROBLEMS: The party control data for state legislatures are often difficult to obtain and the numbers do change over time.
Actual changes may occur due to death, resignation or party switching.
Other changes may occur due to the source of the data.
Few legislative bodies or state election authorities report the aggregate counts by chamber.
This is, of course, complicated by chambers in which only a portion of the seats are up for election in any one year or which have four-year terms.
CHANGES IN TOTAL MEMBERSHIP: Following the 2000 reapportionment, several states altered the number of
members in their legislative chambers.
ND State Senate: 2001: 49 members, 2003: 47 members.
ND State House: 2001: 98 members, 2003: 94 members.
RI State Senate: 2001: 50 members, 2003: 38 members.
RI State House: 2001: 100 members, 2003: 75 members.
