Hartman has spent over 15 years working on behalf of nonprofits, international development, democracy and human rights advocacy, according to a Lancaster Intelligencer report.
GOP Rep. Joe Pitts has represented the 16th district – which includes most of Lancaster and parts of Chester and Berks counties – since 1997.
Christina Hartman, however, believes the demographics of the district are changing, leaving the Congressman out of touch.
Hartman is the only area Democrat so far to declare a bid for Congress in 2016. Rep. Pitts is expected to run for re-election but has held off on confirming a campaign until after this November’s general election – though he registered his candidacy with the Federal Elections Commission in March.
