HARRISBURG — Republican gubernatorial candidates Paul Mango and Scott Wagner are donating heavily to their campaigns, putting up millions of their own dollars for the right to challenge Gov. Tom Wolf, a Democrat, in the November election, according to campaign finance reports disclosed Wednesday.

Wednesday was the deadline for the gubernatorial campaigns to report to state elections officials how they raised and spent money last year.

The campaigns are heading into 2018 with more than $23 million combined in the bank, as the heavy spending season approaches. Mango and Wagner are airing TV ads, likely every day until the May 15 primary election.
