Rasmussen reports that those who the number of those who favor repeal of Obamacare is at an all time low. The new poll shows that only 47% of likely voters favor repeal while 42% oppose repeal. (Apparently, 1% of people live under a rock and couldn't be reached.)
Perusing the poll data, I can see that the highest "favor repeal" has been was 63%, back in May of 2010. Now, giving the benefit of the doubt and adjusting these numbers up or down in accordance with the 3% +/- error rate we have 50% low and 60% high. This is a 10% difference.
Using the 2008 voter data, 64.9% of 225.5 million people voted. That comes out to approximately 146.35 million voters. Using the adjusted 10% difference we come out to a likely 14.6 million people who are crazy-eyed, wishy washy, froot loops who don't know which way is up or down.
But, again, this is just a guess.
