I honestly haven’t wanted to know the details of the whole sordid affair enough to answer that question, although I can’t see how that would matter even if what they did was technically legal wherever it was.
No, most of his voters never cared about his character, but a small percentage were more moderate Republicans for whom such things actually do matter (they’re true believers in “the conservative way”) - possibly just enough to have swayed things.
