You asked and I already answered. In fact I'm pretty sure I answered twice. More evidence that you do not read.<quoted text>
Why do you think that is?
But I'll answer again just for you....
Because it's common sense. If you're trying to persuade someone to your side it makes sense that you would not focus your attention on those "seriously dug in" on the opposition side, as you are not likey ever to change their mind. Instead focus on those who are unsure of where they stand on the issues.
As I said, common sense. And it applies to BOTH sides.
Now don't lie again and claim you never asked anything like you did before. OK ?
