It is true that the Tories made inroads in the Jewish community in the last federal election, but that was either the worst showing or second worst showing for the Liberals ever, depending on how you measure it and the Liberals lost ground among virtually all groups. I'm not convinced the big "realignment" has occurred.
Yet Carolyn Bennett actually improved on her overall share in 2008 vs 2006--go figure...
(Yeah, I know, a post-brake-line-slashing "sympathy vote" may have helped, together with a lesser NDP candidate and less high-profile Tory candidate. Though one significant group Liberals made gains among in Toronto were Peggy Atwood-style urban lefties--thus, surprising results in the Annex, Riverdale, et al)
