Rep. Roscoe Bartlett (R-Frederick) will be the only incumbent Republican from Maryland on the congressional ballot this fall.
The eight-term representative from Maryland's Sixth Congressional District, Bartlett will square-off against former Frederick Mayor Jennifer Dougherty (D).
Sen. John McCain (R-Ariz.) will lead the GOP on the presidential ticket.
Over the years, Bartlett has come to know and "admire" McCain, according to Lisa Wright, the congressman's press secretary.
