Libertarian Doug Marks might be pulling out of the race for the 33rd Senate District after informing supporters that his petition might not survive a challenge.

Marks told supporters Monday on his campaign's Facebook page that the "'parties in power'... have used their exclusionary tactics to have sufficient objections against my petitions to exclude me from having ballot access."

Marks, a Carpentersville village trustee, filed his petition June 25 to run against Republican nominee and Kane County Board Chairwoman Karen McConnaughay, who like many General Assembly candidates in the McHenry County area was running unopposed. Two challengers – Kenneth Cabay of Lake in the Hills and James Abbott of Geneva – filed the objection a week later on July 2.
