Democratic presidential candidates Hillary Clinton and Bernie Sanders are organizing in Pennsylvania as some Republican Party leaders are shifting their support in the contested primary. Pennsylvania’s April 26th primary is four weeks away, and voter registration is now closed with slightly over 4 million Democrats and slightly over 3 million Republicans. State figures show that Democrats raked in more new voters in 2016, but more voters switched their registrations to Republican. Pennsylvanians will weigh in on the Republican and Democratic primaries for president, and pick party nominees for Congress, state attorney general and state Legislature. Sanders and Clinton now have offices open in Pittsburgh, Scranton and Harrisburg.
