Republican candidate Donald Trump won no points for his presidential campaign among Iowan's this week after insinuating that Iowan brains may be addled by GMO crops.

The retweet went out to Trump's 4.64 million followers shortly after a new poll showed Republican candidate Ben Carson was leading the race in Iowa. The tweet in question read:

"@mygreenhippo#BenCarson is now leading in the #polls in #Iowa. Too much#Monsanto in the #corn creates issues in the brain? #Trump#GOP"

Iowans and farmers alike were outraged at the comment, which was quickly deleted later that day and pinned on a "young intern."  Regardless, Trump may not be feeling the "Iowa nice" in the upcoming election.
