Thursday's by elections in Kitchener-Waterloo and Vaughan are said and done, leaving both opposition leaders at Queen's Park talking tough.

PC leader Tim Hudak maintains the reason why the Tories lost a seat they held for 22 years in Kitchener-Waterloo was because a groundswell of what he calls "union muscle" came out to support the NDP.  However, he goes on to say he isn't shying away from any blame when it comes to losing, claiming the buck stops with him because he's the head of the party.

This comes as NDP leader Andrea Horwath calls Hudak's statement that the unions "bought" Kitchener-Waterloo sour grapes commentary. She says the reason why the people chose orange was because they wanted change.

As for what's ahead, Horwath says she will stay focused on bring people's problems and concerns into the legislature and won't be focusing on political ramifications of these byelections.

Hudak says they're "putting on the gas, putting the foot to the floor" with a bold Conservative agenda. He says he's worried the premier doesn't know where he wants to go, repeating he's worried about union influence within the two other parties.
