HARRISBURG, Pa. (AP) — Michael Bloomberg’s presidential campaign has begun hiring staff in Pennsylvania, a late primary state where his chief competitors for the Democratic Party’s nomination have some inroads. Campaign officials said Wednesday that it has hired about 35 staffers in Pennsylvania and has a goal of hiring more than 90 staffers and opening a dozen campaign offices. Pennsylvania is seen as particularly friendly territory to former Vice President Joe Biden. The hiring is part of Bloomberg’s focus on premier general-election battleground states, while other candidates spar in early primary states. Pennsylvania’s primary election is April 28. It has the fifth-most delegates in the Democratic primary.
