HARRISBURG, Pa. (AP) — With Pennsylvania’s ballot seemingly set, Republican candidates for governor are hitting the forum circuit in earnest, working to set themselves apart from a huge primary field with just eight weeks to go in the campaign. Questions about energy, schools and other national political themes have dominated recent forums held by local party organizations, business advocacy groups and other conservative groups. Candidates in the nine-person field — bigger than any seen by Republicans in at least decades — are largely monolithic on the issues, tending instead to try to distinguish themselves by emphasizing the depth of their commitment to those stances. The primary election is May 17. Pennsylvania’s two-time elected state Attorney General Josh Shapiro has a clear path to the Democratic Party’s nomination. Gov. Tom Wolf, a Democrat, is term-limited and has endorsed Shapiro.
