One need look no further than my home state of Arizona to see the result of limp-wristed, nice-guy politicians who have abandoned conservative principles and how they will fare in the current political climate. Senior Sen. and former presidential candidate John McCain is in a battle for his political life as he faces re-election in November 2010.

It is a statistical dead heat. So much for the power of incumbency. But why?...
