Au contraire, libertas, it always helps a responsible moderate to have crazies attacking him, and thus by reaction increasing his support among sanes.
The classic example is the '72 Nixon landslide, but it applies to lesser public figures than president as well.
Ah, so you're a Nixon '72 man too, not surprised.
But LOL @ Tricky Dick being a "responsible moderate".
No, nothing about my post suggested that I view Johnson favorably - I was just using that as an example. The warmongers and other right-leaning movements at the time were viewed as 'extreme' by the middle of the electorate, and it made the rather left-leaning Johnson seem 'responsible' by comparison.
Just wanted to see what that looked like.
