Somehow the Politico comes up with this:
In Illinois, however, Baldermann’s withdrawal from the race could possibly play to the GOP’s advantage. Since the primary has already taken place, the county GOP committees in the district appear like they will be able to appoint a replacement to take Baldermann’s spot on the November general election ballot.
It is true that Illinois’ early primary means the Republicans have plenty of time to recruit someone. At the same time, losing your nominee who had the best name recognition and a solid base of support is not good for anyone.
