The whole story doesn’t seem coherent. If he had drunk himself to the point of the silliness she accuses him of, he probably wouldn’t have been able to “drive her home” (though he could have paid for her cab). She might be a compulsive liar for all we know, a liar that makes up things that don’t even try to make sense, and even when the truth would have served her better.
You’r right, perhaps it is just kikking up a lot of dust and to see what sticks, we all know that most people just read headlines or watch a little of the news on MSM I guess the undecided are those that don’t bother to get themselfs informed, but hear a few accusations here and there and bases their vote on that, and the undesided will likely vote on the latest rumor, we got work to do
