Mayor Michael Bloomberg, an independent who has considered running for president, declared Monday that an independent has a better chance at succeeding in the White House than a Republican or a Democrat . . . at Harvard University on Monday he endorsed the idea of an independent in the White House. “I think actually a third-party candidate could run the government easier than a partisan political president because the partisan political president – yeah he’s got half the votes, but he can’t get the others – whereas the guy in the middle may very well be able to get enough across the aisle,” Bloomberg said.
