Casting corn kernels may not be the most scientific method of presidential polling, but it still reveals some voter preferences in the battleground state Iowa.

Attendees at the Iowa State Fair have been able to cast their vote in the 2016 presidential race by placing corn kernels in a jar at the WHO-HD TV News booth. On the fair’s fifth day, the results so far gave Republican presidential nominee Donald Trump a lead with 56 percent over Democratic nominee Hillary Clinton, who has received 44 percent of the kernels so far.

Polltakers are able to see the results amass before their eyes in clear jars placed on a table. The 12-point lead by Trump came from 24,284 votes. Clinton had 19,418 votes, according to WHO-HD 13.

The unscientific poll, conducted at the fair for the past decade, also revealed that many voters are not happy with the two candidate choices.
