“I wonder how many frum jews will meet , visit and vote for Christine Quinn when she visits Borough Park or Williamsburg”
Probably fewer than voted (by landslide margins) for Mike Bloomberg, who ought to be much more problematic than Quinn. While both support same sex marriage, Bloomberg’s ex-wife and current girlfriend aren’t Jewish, and neither are his kids. Quinn OTOH violates absolutely no issur by having a female partner because neither is Jewish.
And as I alluded to earlier about half of American Orthodox Jews voted for Mitt Romney, a polytheist.
