See post 61; not enough conservatives left within the city limits for one to make a viable run for Miss Congeniality, let alone elective office.
Also, let me add factor 8; a compliant local media. They’ll run down occasional instances of really disgusting corruption, but by-and-large, they stay on the machine’s plantation. It took years to nail Blago, and most of the really corrupt party movers enjoy a comfortable retirement in Florida and the like.
The identification of the race of numerous perps (especially in flash mob incidents) is routinely ignored for fear of upsetting the party bigwigs who need tha patina of racial harmony to keep out of trouble, and a double-standard based on party affiliation is so obvious it’s laughable: when Jim Ryan ran for senator (against BO) the Trib forced open sealed divorce records to drive him out of the race; when BO ran for anything, all we heard from them was how glamorous he and his wife and his daughters were.
Jim Ryan didn’t run for the U.S. Senate. That was Jack Ryan.
