The Ontario Liberals suffered an upset loss last night in a by-election.
The NDP captured the normally Liberal riding of York South-Weston, meaning Premier Dalton McGuinty and his braintrust will go back to the drawing board.
And if I know my Liberals, Dalton will seek to stem the socialist threat on his left flank by becoming more of a socialist himself.
This strategy is all the more likely since PC leader John Tory is not threatening him on the right flank.
In other words, Ontario taxpayers beware: Dalton is coming after your wallet!
