Rick Perry will intensify his attacks on Donald Trump in a speech Wednesday in Washington, D.C., in which Perry will call Trump’s campaign for president “a cancer on conservatism.”

“Let no one be mistaken: Donald Trump’s candidacy is a cancer on conservatism, and it must be clearly diagnosed, excised and discarded,” Perry will say, according to excerpts of his speech provided to RealClearPolitics. Perry will deliver the speech as part of a forum organized by the pro-Perry Opportunity and Freedom PAC.

As Trump continues to enjoy strong standing among Republicans in public polling, Perry will aim to dent the public perception of Trump by warning that he is “a barking carnival act” with the potential to gravely damage the Republican Party in the long term.

“(Trump) is without substance when one scratches below the surface,” Perry will say. “He offers a barking carnival act that can be best described as Trumpism: a toxic mix of demagoguery, mean-spiritedness and nonsense that will lead the Republican Party to perdition if pursued.”
