1.) This thread should be merged with the other Hudak-OPC thread into a general Ontario PC related thread.
2.) Hudak's success/failure will rest on his ability to highlight McGuinty's failures. Its a truism that people generally vote against one party as opposed to for another, so Hudak's job is to show people why McGuinty is bad. That was the problem with John Tory, 90% of his policies were identical to McGuinty's and he failed to take advantage of possible weaknesses at the time (i.e. health premium, unfair support of the 'big 3', rising spending or such).
3.) McGuinty will have had, basically, an 8 year free ride with respect to opposition. There is a general perception that 'he hasn't done anything wrong.' That perception has to be the first target for Hudak. It's not necessarily untrue, but its more a matter of perception then anything else. For instance, it has been quite clear that the manufacturing industry has long term macroeconomic problems. That's been clear since McGuinty's first term, and yet his government's policy towards this issue is undeniably reactionary. I'm not saying it's an easy topic, but if nobody makes the case that McGuinty has failed here then nobody will think that. Hudak wouldn't even have to, really, propose an alternative. Just make the case that McGuinty failed.
4.)Other issues; failure to address Ontario's energy needs, failure to deal with the paper industry, failure to meaningfully lower interprovincial trade barriers, failure to lower marginal taxes on capital. I'm not sure on the polling data here, but opposing McGuinty's planned daycare/kindergarten policies may be successful. It's a polarizing issue, and it's conceivable that some kind of an early education credit (worth the approximate value of quality daycare), available to stay at home moms as well as those who choose daycare, could have greater popularity amongst parents than unionized public day care. I'm still waiting for someone to propose merging the catholic & general public schools.
