Morella. She had the most liberal voting record of any Republican in Congress since....probably another Marylander, Mac Mathias.
But a 20/25% is the best we could ever hope for from from stinking Montgomery County.
Morella was just horrid. I was looking at her next-to-last-year in office, 2001, and she got a 12% Conservative rating, which was identical to Babs Mikulski. She even went so far as to file an amicus brief on “gay” marriage. At some point, you have to ask what you get electing people as Republicans virtually indistinguishable from the far-left of the Democrats. It was like losing Curbelo in FL, his record was just as horrid.
Charles Mathias hailed from Western MD, which made it all the more baffling that they’d elect such a far-left RINO from a Conservative district (which later elected Conservative Dem Goodloe Byron, and his widow, centrist Dem Beverly Byron, neither of whom could even be nominated as a Dem today - and indeed, she was defeated in the ‘92 primary and that allowed the superb Roscoe Bartlett to succeed her). Mathias was so bad, he got a 0% rating from the ACU in his last year in office in 1986 (which put him to the left of Babs Mikulski, who got a 5%). He passed on switching parties, though he could’ve become a Dem without blinking.
