Based on the poll I saw, Christine Elliot looks like the most popular choice among voters, with Mulroney 2nd and Ford third, with all three showing a strong chance of beating Wynne and Horwath in the election.
I was reading yesterday that Ford was campaigning about the sex-ed curriculum. I assume this means he intends to fire up the yokels and rednecks and fight the leadership campaign on social conservatism. This will probably hurt the party's image among the general electorate.
