"It would be useful to advocate that once a candidate is chosen, Republicans unite behind that person, because that person will be better for the country than any democrat. "
Yes, it would be.
But the Rudy haters are declaring that they won't support him, even if he is the Republican nominee, they will stay home, vote third party, some even said that even they they would actively work against him, some even said that they actually would prefer Hillary. I even asked the question, whether they would vote for him if their fav Hunter would endorse him, and they said no.
So how conservative do you think it is to help Hillary get into the White House?
In that case we should nominate someone like D. Hunter who doesn't have a significant percentage of conservatives who will NOT vote for him under any circumstances. In other words, we should nominate someone electable. As for Rooty, sure, I'd vote for him, just not in this lifetime.
