If Newt will join in with Romney to purge the nation of the worst president the U.S. has ever had he will go down in infamy and possibly have a real shot in 2016. We cant take even one more year of this lying Muslim scum in office.
"Infamy" means "extremely bad reputation, public reproach, or strong condemnation as the result of a shameful, criminal, or outrageous act."
Is that the meaning you had in mind?
