We're dizzy from watching Ontario Liberal leader Dalton McGuinty spin his position on the Tories' tax credit for parents who send their kids to private schools. McGuinty now says he's opposed to the Tory initiative and will scrap it if elected. But under pressure from Jewish leaders, he also says there's a "fairness issue." Dear Dalton: yes, there is. It's called the public school system, and we're not sure we can trust you to stick up for it.
