[naviga:h3]Lamb, Saccone in line for primary[/naviga:h3]

HARRISBURG — Democrat Conor Lamb and Republican Rick Saccone each could see a primary contest in new congressional districts after they battled for an existing district in southwestern Pennsylvania.

Lamb’s campaign said Friday that he will seek a full term in Congress in a new district west of Pittsburgh against three-term Republican Rep. Keith Rothfus.

Democrats Elizabeth Tarasi and Ray Linsenmayer say they’re gathering signatures to get on May’s primary ballot, too.

Lamb holds a slim lead over Saccone after Tuesday’s special election to fill the remaining 10 months of disgraced ex-Republican Rep. Tim Murphy’s term. Vote-counting is ongoing.

Saccone and Republican state Sen. Guy Reschenthaler are gathering signatures in a new district in southwestern Pennsylvania’s corner. The deadline to file signatures is Tuesday.

[naviga:h3]Lt. governor’s residency disputed[/naviga:h3]

HARRISBURG — Pennsylvania’s lieutenant governor faces a legal challenge over his residency that aims to derail his re-election campaign.

A petition filed this week in Commonwealth Court alleges Democratic Lt. Gov. Mike Stack violated election rules by claiming he resides in his mother’s home in Philadelphia when he actually lives in a state-owned mansion at Fort Indiantown Gap, near Harrisburg.
