But the concern for Bloomberg is not the amount of money he personally invested in the effort to save the seats of two Colorado state senators -- an effort that failed when both were ousted from office Tuesday by voters apparently displeased with their roles in passing gun control legislation.
Instead, the overriding worry for the 71-year-old mayor is that the defeats seem to underscore his increasing inability to nationally impact the public policy issues he’s most involved with.
On the heels of his failed $12 million effort to implement stronger gun laws on the national level -- a crusade that some observers have said harmed efforts to pass background-check legislation -- Bloomberg has become a favorite punching bag for the NRA and other small-government advocates, who have singled him out as an enemy of personal freedom.
