Consider it a preview of the general public as they actually start learning more about Guiliani, looking past the "America's Mayor" label to see what a horrible President he would make.
Also realize, the main reason he's in such a "lead" is due to the lack of any one opponent coming out of the pack. That will change, and when it does, that "lead" will vanish, almost overnight, assuming Guiliani doesn't blow it himself with some of the loose cannon comments he's prone to make.
You must be kidding. Pure wishful thinking. It been a non-stop “throw everything you can and see what sticks” kind of national campaign against Rudy for the past several months. Google Rudy’s name and 9 out of 10 articles are hit pieces. There’s a desperate attempt to drive down his poll numbers. And in spite of that, Rudy’s Real Clear Politics national poll average remains high at (31.8%), versus (19.6%) for McCain, (10.6%) for Thompson, and (10%) for Romney. And he also continues to have the highest favorable rating of all candidates. I hope there's a Plan B.
