While I appreciate that he dropped out, an election is not only determined on election day or even a month out. Elections are affected by all the politics involved during the campaign.
Who runs, who supports whom, who works for whom, who contibutes to what campaign, etc. are all dynamic factors affecting an election.
Running the mayor as a bogus candidate distorted the election. It is a matter of degree just how much. What I'm objecting to is this distortion. I would like the FBI to catch crooks with the minimal possible effect on the lawful election process.
Which distortion is larger, vote buying or running a fake candidate during the primaries?
How else does one catch corruption of this nature? How about the FBI going up to a legitimate candidate and entrapping them into buying votes?
