That was one, also the 'Rats winning a number of traditionally GOP seats that they shouldn't have, and the 6-year curse of a 'Rat administration (if you count JFK-LBJ as one). The GOP, ironically, would've had at least 8 or so fewer seats going into 1966 had it not been for them winning ultra-'Rat Southern seats in '64 (in AL, for example, the all-'Rat delegation in 1962 (as it had been since 1901) became majority GOP (5-3) in one fell swoop, but then dropped to 3-5 'Rat in '66, and the GOP would not regain a majority there until 1997). Some of these, of course, were temporary gains, and wouldn't be solidified for, as with AL, until the '90s.
