REDISTRICTING AND INCUMBENT REELECTION SUCCESS IN 5 STATE LEGISLATURES

Does redistricting affect the election success of incumbents? Does it affect the electoral fortunes of political parties? These questions ar e examined in five states that used different redistricting processes in 1991-1992 and in two states where the redistricting process changed from 1981-1982 to 1991-1992. In states where redistricting was highly partisan, parties controlling the process gained politically. In stat es where redistricting was bipartisan, that is, both parties were invo lved, neither party gained an advantage. Likewise, where redistricting was nonpartisan, that is, parties were excluded from the process, nei ther party gained an advantage and the outcome was least hospitable to incumbents.
