Thanks for your clarification. I guess if Powell had only won by a handful of votes they could've refused to seat him, and once he had been seated they could with a 2/3 vote expel him, but they couldn't refuse to seat him at the beginning of a Congressional term just because they thought he was unsavory. Is that about right?
Yeah, that's correct.
I guess the House could have claimed that, even though Powell won handily, his election was due to voter fraud and thus exclude him, but there would have been hell to pay politically had the House subverted the will of the voters in such a crass and unethical manner; I mean, how much fraud would you need to prove in order to overturn an 80%-20% election?
