These maps are too favorable to Reagan. McCarthy was not perceived as the "hippie candidate" to the extent that McGovern was in '72; he actually had some crossover appeal to suburban Republicans and polled well against Nixon in pre-convention "trial heats". He would've done badly in the South, but so did HHH, who only carried Texas narrowly on LBJ's coattails. In addition, Reagan was less than two years into his gubernatorial term and probably at the height of his "Goldwater 2" image nationally.
I think it would have gone to the House:
Reagan 248
McCarthy 245
Wallace 45
