Why Does the Makeup of State Government Affect Redistricting for Congress

Why does the makeup of state government affect redistricting for Congress?

A) State legislatures often determine the boundaries of congressional districts.
B) Nomination for office occurs through state legislatures, and divided government produces more moderate candidates.
C) Governors draw maps on their own, and thus parties must control the governorship if they wish to have an effect.
D) State legislatures approve judges, and therefore the judges that draw the map respond exclusively to the partisanship of the legislature.
E) Commissions draw all maps, and thus the makeup of state governments does not affect congressional redistricting.
