I don’t know how Conservative Martin’s record was. One I do know about was the legendary Laurence Curtis, who was considered an unapologetic Conservative. The legislature deliberately wiped his seat out in 1962 after 10 years in Congress, and he tried 4 more times to get back to Congress (he ran against George Lodge to face off against Ted Kennedy (where he lost by only 45-55% in the primary despite having the establishment against him). He ran in the 3rd against Philip Philbin in 1968, in the 9th against Louise Day Hicks in 1970, and in the 4th in 1972 (which was the 3rd previously, losing in the primary to a RINO, liberal Jewish State Rep. Martin Linsky, who almost beat Father Drinan in the general. One Avi Nelson was also in the primary, and he nearly beat Ed Brooke in the ‘78 GOP primary)).
I see Nelson and Curtis together had way more votes than Linsky. Too bad.
