Democrats occupy the offices of New York City comptroller, public advocate, Council speaker, 46 of 51 Council seats, and four of five borough president offices. His victory in 2009 was assisted by the numerous Democratic elected officials who crossed party lines to endorse Bloomberg or stay officially neutral.
Likewise, Democrats holding 13 of 14 congressional seats, 22 of 24 State Senate seats, and 59 of 61 Assembly seats impacts his relationship with both Washington and Albany. His only political friend in Washington is Staten Island Congressman Michael Grimm.
Others assisted in different ways when actually endorsing fellow Democrat Bill Thompson for mayor, effectively sitting on their hands and only going through the motions by nominally campaigning for him.
Yesterday's old friends of Bloomberg have become strangers with no incentive to help him govern during his final term. Democrats, including Speaker Christine Quinn, Comptroller John Liu, Public Advocate Bill Di Blasio, Manhattan Borough President Scott Stringer, Congressman Anthony Weiner, and former comptroller and 2009 mayoral candidate Bill Thompson are already jockeying for positions in the 2013 municipal elections.
Bloomberg abandoned the Republican Party whose ballot line he "rented" for convenience in winning a third term. He has continued his past track record of doing little to help finance and run serious Republican challengers against incumbent Democrats.
Bloomberg's 2009 reelection strategy was deliberate in not spending any significant time campaigning and fundraising for GOP challengers. He didn't want to increase turnout of registered Democrats or offend incumbent Democrat Party public officials. As a result, he has virtually no GOP allies in City Hall.
There is only so much love Bloomberg can buy with his billions.
