HARRISBURG (AP) – Third-party candidates in PA for governor and U.S. Senate filed paperwork to get on the Nov. 8 general election ballot, potentially making a crucial difference in the high-stakes races. Monday’s close-of-business was the deadline. The state’s online candidate list shows that three parties – the Keystone Party, the Libertarian Party, and the Green Party – all have candidates who filed voter signatures for governor and U.S. Senate. A third-party candidate’s draw in a general election could make a difference in a close race between the major party candidates. A Fox News poll conducted in late July showed Democrats polling higher than Republicans in the gubernatorial and U.S. Senate races at this time.
