A new poll finds that voters will put most blame on Premier Dalton McGuinty if Ontario is thrown into a snap election.

MPPs will vote on the budget bill this Wednesday.

Last week, the premier threated to dissolve government if the opposition parties didn't let the bill pass intact. He toned down his language in a letter to NDP leader Andrea Horwath yesterday, asking the NDP to promise in writing that it will keep an earlier agreement to approve the budget.

The Toronto Star reports that a Forum Research poll conducted on Friday shows 44 per cent of voters would blame McGuinty for forcing an election, while 23 per cent would point their finger at Horwath.

Her approval rating is also down from 47 to 39 per cent in less than two weeks, while McGuinty's has gone up just one point - from 27 to 28.
