Brown said she is looking forward to the convention.

"We're going to get a great nominee out of that," she said.

Rep. Timi Brown-Powers was also excited about the potential Democratic nominees.

"I was very pleased with the four candidates who stepped up to run," Brown-Powers said. "I thought that they all brought something to the table and I think all of them have something to learn, as did I when I started this."

Libertarian candidate Fred Perryman announced his candidacy to The Courier via email.

"We have an opportunity to represent our district with a candidate that respects the rights of all citizens regardless of which party we affiliate with," he wrote."I believe I am that candidate."

Rep. Bob Kressig was a Iowa House legislator along with Danielson, and has decided not to run for the open seat.

"I didn't run because I think our chances in the house are better at being a majority and I'd love to be in the majority again," he said.

Kressig said special elections traditionally have lower voter turnout.
