Be glad too. Extreme means the furthest from the centre of a given point. But what extreme means to me politically in the Republican Party, is any candidate that is so far to the right, that they can not beat Hillary Clinton in the Presidential election. If Hillary wins the Presidential elecion it will be "extremely" (meaning severely or seriously) devastating for this country.
The question is will the grass roots get behind a candidate? There are very, very many people who believe that Giuliani needs to be the candidate because he can beat Hillary. My suspicion is that too large a percentage of typical Republican voters stay home if Rudy is the nominee. Same for McCain, same for Ron Paul.
The question becomes, what energizes the grassroots to get behind a candidate? I believe it's conservative principles and not "electability."
