By the time of Indiana's primary, Kerry had already secured the Democratic nomination after several decisive victories on
Super Tuesday in March. Indiana holds
open primaries, meaning voters do not have to be registered with a certain political party to vote for a candidate in that party's primary (i.e., non-Democrats vote for candidates in Democratic primaries in Indiana). Ballot returns broken down by
congressional district shows the extent of Kerry's domination; there was not a single district he did not win the vast majority of votes in on the day of the primary. Edwards came in second place in all districts. Dean came in third place in all districts, narrowly edging out Clark for the third-place position by just a few hundred votes in
Northwestern Indiana (which contains Indiana's share of the
Chicago metropolitan area),
Northeastern Indiana, and
Central Indiana (excluding
Indianapolis). Clark came in fourth in all districts. Two more candidates,
Dennis Kucinich and
Lyndon LaRouche, were on the ballot for
Hoosier voters, but in most districts, they both failed to garner more than a couple hundred votes apiece. LaRouche was able to defeat Kucinich narrowly in the eighth district, roughly corresponding to
Southwestern Indiana, but Kucinich defeated LaRouche everywhere else in the state. ==References==
