The Chicago Board of Election Commissioners is reporting that voter registration in the city has increased by almost 20,000 since February.

The 1.4 percent increase in registered voters is no doubt a result of the mayoral runoff election between incumbent Rahm Emanuel and challenger Cook County Commissioner Jesus 'Chuy' Garcia. The 18 aldermanic ward runoffs could also be encouraging eligible voters who were not previously registered to head to the polls.

The wards that have seen the largest increases in voter registration are: the 46th (2.35%), 1st (2.31%), 11th (2.22%), 25th (2.13%), 43rd (2.05%) and 32nd (2.02%). The 1st, 25th and 32nd Wards do not have aldermanic runoff elections.
