Gallup pollings has been really GOP-friendly so far this cycle.
http://argojournal.blogspot.com/2012/08/poll-watch-gallup-2012-daily_28.html#more. Read this. Nate Silver may be down on Gallup, but they haven't necessarily been "GOP friendly." Barack Obama led Mitt Romney for 42 out of the 45 days prior to the Ryan selection. How is that "GOP-friendly?" Out of the 130 total days Gallup has been tracking the race, Obama has led or tied Romney 88/130 days. Romney has led or tied Obama 68/130 days. Again, where are you getting this "Gallup is GOP-friendly" meme from? If you're ONLY looking at the past 2 weeks, then okay. But other than that, facts don't bare it out.
