Sorry Sochead, Johnson will be insignificant. I figure 3% or less nationally, and that is being generous. I actually think he takes votes out of the Obama column more than Romney. No one I know of, who is voting for Johnson, would have EVER voted for Romney. But a good many of them are the kind of idiots who were enamored with Slick Barry. I can see a lot of Deaniacs supporting Johnson, for some reason. But I don't think he has ANY effect on Romney one way or the other, because those voters weren't ever going to vote for the GOP candidate anyway.
I will also add here, a whole helluva LOT will be determined by turnout. The way I see it, the liberal base is just not energized like they were in 2008. When people like Bill Mahr are no longer on board, you know there is a problem in paradise. Meanwhile, this is the Tea Party's proverbial "moment" and I expect we will see massive turnout across the country for Romney. If that's the case, he could win in a landslide.
