The thing is, that kind of stuff would only matter if it takes in people who would otherwise be voting for the Democratic candidate (probably Clinton), or if it motivates people who would otherwise not be voting into getting up and voting for the Republican.

And at the same time if those people outnumbered those for whom the effect of those kind of blatant lies might be to make decent people less likely to vote for the Republican and stay-at-homers likely to get out and vote Democrat.

Sounds like a very risky strategy.
