I agree - point McCain. He just ripped the spotlight from Obama. It was already reported that Obama didn't get a bounce in the polls and this has now shifted the media spotlight completely away from him.
My bet is she will get hammered during the debates (talk about lack of experience). I also think he wanted to go with experience especially around the economy and go with Romney. He got scared after the Dem convention and decided he needed to do something risky that might pay off big and win over Hillary fans. I think it actually shows a little panic and in the end won't pay off like he wants.
What does "gauge" mean anyway? As used here gauge means the number of round lead balls the same diameter as the inside of the barrel (aka the bore) that it would take to weigh one pound. It takes 12 lead balls the same diameter as a 12 gauge barrel to weigh a pound. The smaller 20 gauge would require 20 balls of that barrel diameter. The larger bore 12 gauge would require 12 lead balls of the bore diameter to weigh one pound.
In general the number of pellets in a shotgun shell...
