<Looking at growth in posts and joiners in social networks. Quick count.
Obama gains around 1% supporters, a sluggish movement, where maybe many already have showed their support. The against side of Obama also appears sluggish
McCain gains 5%+ supporters but also the against side is growing with around 6%+.
So McCain is the one in the spotlight at the moment (and we see that in media). I think I can see more "against McCain sentences" than "for Obama sentences".
