QUEBEC -- Jean Charest's resignation from politics has started the speculation rolling on who will replace him as Quebec Liberal leader.
   So far, no one is saying categorically they want to head the party, which is now the Opposition after this week's provincial election.
   Finance Minister Raymond Bachand said today he's leaving the door open.
   Pierre Paradis, who lost to Robert Bourassa when he won the job for the second time in 1983, says he hasn't ruled it out.
   Transport Minister Pierre Moreau says he has nothing to say on the matter, while outgoing justice minister Jean-Marc Fournier says he's not interested although he isn't excluding the possibility of being interim leader.
   Charest resigned yesterday after the Liberals lost the election to the Parti Quebecois. He also went down to defeat in his own riding of Sherbrooke.
