The media has been trying to maintain all year that there has been this horse race between Romney and Obama. The truth is that the horse simply won't dance, that's because it's dead, and every time that Romney tries to sell the Republican horse liniment the smell gets worse.
The current headline that Obama leads in some battleground states and is tied with Romney in the rest is simply not true. They are now defining 'tied' to mean that Obama doesn't lead by more than the margin of error in the polling. A margin of error number that gets bigger every day. How do you 'legitimately' increase the margin of error number? You simply poll a smaller number of people each time, this is then interpreted mathematically to be less accurate, so you get a bigger margin of error percentage number.
They don't mention that there are dozens of polls being taken using different methods and when to aggregate the results from more and more sources the margin of error approaches zero. You can't include Republican fluff polls in the equation when you do this, or you could prove the world is flat.
Even the right-wing pundits have given up cheering for this horse, and are simply trying to keep the Republican myth alive that they represent anything more than the naked greed of the 0.01%. These days the only sound coming from the Republican stables is the buzzing of flies.
