Four Illinois governors have been sent to prison: 3 Democrats and 1 Republican. The Democrats may add to their lead as the incumbent Quinn, who succeeded his impeached running mate Rod Blagojevich, is now under Federal investigation.
Nobody in Illinois is enthusiastic for RINO Rauner. It is simply that Quinn is that bad.
However, a significant portion of the Republican combine opposed him during the primaries and some 'Republican' POS state senator ran against him on money raised by the Dems and the public employee unions.
He is widely hated by the Combine, so there's some hope he'll improve things.
