If 7 Was 9

Q:	How many candidates in the Sixth Congressional District does it take to screw in a lightbulb?
A:	Who's counting?

Haha, there is already a crowded field of candidates in the Sixth Congressional District. The Daily Herald counts seven:

The already packed field of Democrats seeking to unseat U.S. Rep. Peter Roskam in the 6th Congressional District got a little more crowded Thursday when Sean Casten, a scientist and clean energy entrepreneur from Downers Grove, announced he's joining the race for the Democratic nomination.
Seventh Democrat announces plans to challenge Roskam

While the Pioneer Press recognizes nine:

Downers Grove resident and scientist, Sean Casten announced Thursday plans to run in the 2018 Democratic primary for U.S. Rep. Peter Roskam's 6th District seat. So far, nine Democrats are planning to seek the nod to appear on the ballot
Downers Grove scientist is ninth Democrat to announce run for Roskam's seat

At the rate things are going, there will be more Democratic candidates for the Sixth Congressional District than there are voters. Statistics like those hardly bode well for incumbent Republican Congressman Peter Roskam.

The good news for Roskam (Lake County's vestigial Congressman) is there is a theoretical limit to the number of candidates that can appear on a primary ballot. Divide the number of voters by the number of petition signatures required, and your LakeCountyEye reckons there can be no more than 1,000 names on the Democratic ballot. Give or take a few.

Note to Ops in the Sixth Congressional District: Your petition period began last Tuesday.

Just sayin!
