An eagle-eyed Corner reader in the Windy City writes in:
“I live in Chicago and know 118 N. Clinton well. It is the headquarters of Uquhart Media, run by Dan Proft.
He is a political consultant for a number of clientele, including the former US Senate nominee Jack Ryan. This may explain the origination of the “You Don’t Know Jack” slogan, as that was one of the ways they chose to introduce the candidate.”
Uquhart Media is a GOP lobbying/consulting firm.
Another reader notes that the Senate campaigns of both Ryan and Alan Keyes were housed in the building.
