"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
McCain won’t be helped in the general election by Hispanics as he was in the Florida primary (or further primaries?). Some pro-border security Republicans and independents may bite the bullet and vote for him, but he’ll lose a substantial part of his conservative base. Other independents may vote for him over Hillery, but I question their numbers against disenfranchised conservatives.
What could be the deciding factor is how the Democratic base deals with a Hillary candidacy after her handling of the delegates issue. Against Obama, McCain wouldn’t stand much of a chance. The support for America’s first black (real) candidate will be just too powerful.
