Late last night the Chicago Board of Elections made their ward by ward (and precinct by precinct) numbers available and I was able to plug those numbers into the tracker I would have used had those numbers been available earlier in the night. Most of these insights are derived from a quick glance at the tracker.

2015 Chicago's Mayor's Race Election Night Tracker

A few thoughts:

• In majority AA wards (by census) Emanuel (42%), Garcia (26%), Wilson (22%), Walls (6%), Fioretti (5%). In wards with an AA majority 32% of the vote went to candidates that will not be in the runoff so it will be interesting to see where these voters fall.
• In majority Hispanic wards (by census) Garcia (52%), Emanuel (37%), Fioretti (7%), Wilson (3%), Walls (1%). Only 11% of this vote went to candidates not in the runoff.
• In wards with a white majority (by census) Emanuel (52%), Garcia (34%), Fioretti (10%), Wilson (4%), Walls (1%). 15% of this vote went to candidates not in the runoff.
• In wards with no majority (by census) Emanuel (49%), Garcia (35%), Fioretti (9%), Wilson (5%), Walls (1%). 15% of this vote went to candidates not in the runoff.
• Reminder, the "2011" numbers in my tracker were reconfigured to match the current ward maps. In the majority AA wards the 2015 numbers for Emanuel were about 12-20 points lower than 2011.
• It was harder to draw conclusions about the Hispanic majority wards, some showed Emanuel improvement (10/13/14/31), others big drop (22/25/33/35).
• In only a very few wards did Emanuel improve over his 2011 numbers but somehow in the 13th ward he did almost 15 points better. Interesting.
• It appears that 19 aldermanic races are headed to an April runoff (2, 7, 10, 11, 15, 16, 18, 20, 21, 24, 29, 31, 33, 36, 37, 41, 43, 45, 46). So while the overall numbers were Emanuel (45%), Garcia (34%), Wilson (11%), Fioretti (7%), Walls (3%), if my math is correct in just the 19 wards that are headed to aldermanic runoff the numbers were Emanuel (46%), Garcia (31%), Wilson (12%), Fioretti (8%), Walls (3%). The Mayor did slightly better than average in these 19 wards but there is also 23% of the vote in these 19 wards that went to candidates that won't be in the runoff so it will be interesting to see where those voters fall. Obviously these 19 wards are likely to have higher turnout in April than the wards without Aldermanic elections.

Here are some of the big questions going into April:

1. Of the 21% of voters who voted for one of the candidates who didn't qualify for the runoff, where does their support go? These voters are largest among wards that have an AA majority by census so you'll likely see a significant focus of the campaign in those communities between now and April.
2. Can Garcia expand on his 52% of the vote in Hispanic majority wards and can the Mayor continue to make inroads among Hispanic voters despite having a Hispanic candidate in the race?
3. What happens in the 19 wards with Aldermanic runoffs and how does that affect the Mayor's race?

Now we have a six week sprint until April.
