Some came to the conclusion a lot faster. 2008, 2010, or even earlier. Others may take a few more cycles to finally realize it.
Me? I was very slow, but even I have had enough. 2010 election decided for me.
I agree, if Romney gets it I will no longer be a Republican or identify myself as such. Do you think there is a single Republican official who can answer the question whether zer0 was ever a citizen of Indonesia? These cowards didn’t even have the guts to pursue that! I’ll tolerate Gingrich or Santorum, if it’s Romney I’m out.
