A Republican in Arkansas who wrote that slavery was a "blessing in disguise" compared Democrats to Nazis on Thursday.

"Does all of this political propaganda being put out by Gov. Mike Beebe, Attorney General Dustin McDaniel and others remind you, even a little bit, of how Hitler took control of the minds of the German people in the 1930s?" state Sen. Jon Hubbard wrote in a letter to The Jonesboro Sun.

Hubbard, GOP House candidate Charlie Fuqua, and GOP Rep. Loy Mauch have all recently faced a backlash for controversial statements that were uncovered by the press. The comments have been condemned by Democrats and the Republican Party of Arkansas said it will no longer support the candidates.

Hubbard claimed the owner of the restaurant where Fuqua had planned a fundraiser had canceled the event, fearing it would be the site of a protest.

"Regardless of one's political persuasion, this reeks of Nazi-style political intimidation, and it will grow totally out of control if allowed to run unchecked," Hubbard wrote. "Is this what we want here in Jonesboro, in Arkansas or in the United States of America?"

Hubbard wrote in 2009 that , "the institution of slavery that the black race has long believed to be an abomination upon its people may actually have been a blessing in disguise" because their offspring eventually gained U.S. citizenship. He also said immigrants, both “legal and illegal,” will eventually have to be rounded up and killed.

In 2007 and 2009 letters, Mauch had called Abraham Lincoln a “war criminal” and asserted that “Jesus Christ did condone slavery.”

Fuqua, a former Arkansas state representative, had called for deporting all Muslims from the U.S. in his 2011 book, “God’s Law: The Only Political Solution.” The book also suggested a “death penalty for rebellious children” to protect the “foundation of family discipline.”
