Will Jonathan Dean be the Democratic nominee for Senate in Illinois?

Reasoning

Jonathan Dean is a legitimate Democratic candidate for U.S. Senate in Illinois (replacing Dick Durbin), running as a Chicago-based lawyer and solar energy entrepreneur. He has a campaign website, media coverage, and is participating in candidate questionnaires. However, the Illinois Democratic Senate primary is highly competitive with several higher-profile candidates. The evidence shows Dean is a real candidate with some media presence, but there's no indication he has significant polling support, major endorsements, or fundraising that would make him competitive against better-known candidates. The baseline probability of 0.15% is very low, but given that he is a real, active candidate with some media coverage, a slight upward adjustment from baseline is warranted. Still, his chances remain very low given the competitive field.
