While Michael Bloomberg is dining with the Manhattan Republican County Committee tonight—where, according to a source, Mitt Romney will be a speaker—his Democratic challenger, City Comptroller Bill Thompson, will be getting an endorsement from an assemblyman in the Bronx.
Thompson's campaign announced that Assemblyman Peter M. Rivera, "the highest-ranking Latino elected official in the Assembly," will endorse Thompson at 6:30 p.m. at 2151 Newbold Avenue.
Bloomberg's dinner tonight is taking place at the Grand Hyatt. It's closed to the press, according to organizers.
Bloomberg's dinner will be interesting, since he and Romney clashed directly on the issue of immigration during the presidential race last year, after Romney referred to New York as a "sanctuary city" (to be fair, Romney was going after Rudy Giuliani, not Bloomberg).
Romney is also something of a darling of conservative Republicans. Bloomberg is, generally, not.
