Bruce Rauner still has a considerable lead over the other three GOP candidates looking to win the nod for governor.  A poll conducted by the Paul Simon Public Institute reveals more than a third of likely GOP voters aren’t sure who they’ll be supporting yet, but 32-percent of them are backing Rauner.  It’s a toss-up for second place, with Brady snagging 12-percent of the respondents’ support and Kirk Dillard grabbing eleven-percent.  About ten-percent say they’re backing Dan Rutherford.  When it comes to facing Governor Quinn, the poll puts all the Republicans on top, except Rutherford.
