I disagree with BK24. Bloomberg was a lifelong Democrat before deciding to register as a Republican. Ever the opprtunist, he found this to be an easier path to securing a major party mayoral nomination. After retiring from the military, Colin Powell dithered before announcing any party affiliation. All this, while be courted by both major parties. When he finally announced that he was a Republican, he claimed to be a "Nelson Rockefeller Republican". Both men exemplify the concept of RINO.
