Liz Harrington said even though the two candidates represent very different policy ideals, both speak to a group of voters that have largely been ignored.

“You shouldn’t just brush off a side,” Harrington told Hill.TV. “That was what 2016 was largely about.”

“It was a dissatisfaction with Washington,” she added.

Harrington also argued that Republican Party already has an advantage going into November’s election, saying it is more united than the Democrats.

“The Republican Party today is so much more united than the Democrat Party is, and I think that’s going to be very beneficial going into November,” she said.

Her comments come as Iowa voters prepare to prepare to head to caucuses across the state Monday night.
