HARRISBURG, Pa. (AP) — California billionaire Tom Steyer and former South Bend, Indiana mayor Pete Buttigieg are the first Democratic presidential candidates to file signatures to get on Pennsylvania’s primary ballot. That’s according to information from the state election office Friday. The other campaigns have through 5 p.m. on Tuesday to file 2,000 signatures of voters who are registered Democrats to get on Pennsylvania’s April 28 primary ballot. Pennsylvania is a late primary state, but nonetheless could be important if the eventual nominee remains in doubt past March.
