Here's a fascinating interview that Fox News' Greta van Sustern did on Wednesday night with former UN ambassador John Bolton. In the first part of the interview, Bolton endorses Mitt Romney for the Republican nomination, saying that Romney is the most conservative candidate who is capable of defeating Barack Hussein Obama. While I believe that Santorum and Gingrich are both better on Israel (and a whole bunch of other issues) than Romney, I can see Bolton's argument.
