You've provided two characteristics to a presidential candidate that may very well be mutually exclusive in 2008. On the one hand, you suggest that the most important job of the president relates to national security. But then you also insist that the Republican candidate must be "electable."
How electable would your ideal "national security" candidate be if a substantial part of the U.S. electorate in 2008 doesn't consider national security to be the most important issue?
The electorate has issues with the Iraq war, but not with the issue of national security.
In fact the Democrat Trojan Horse is that they can do national security better. Hope to win on that lie and then force their domestic agenda down our throats.
The Republican that will win will take the national security issue away from any Democrat BS- that's Giuliani.
