text_A: In the 1994 election, North ran a victorious campaign for the United States Senate as the Republican Party candidate in Virginia. Republican senator John Warner of Virginia endorsed Marshall Coleman, a Republican who ran as an independent, instead of North. Coleman lost, garnering only 11 percent of votes, while incumbent Democrat Charles Robb, a son-in-law of President Lyndon B. Johnson, failed to win reelection after receiving 43 percent against North's 46. North's candidacy was documented in the 1996 film "A Perfect Candidate".
text_B: Does it sound like the title "A Perfect Candidate" may have been chosen with deliberate irony, since North ultimately failed to win his party a Senate seat?
NO.
