Des Monies, Iowa (CNN) - Iowa state Republican Chairman Matt Strawn said his state is experiencing an "unprecedented" level of fluidity in picking which Republican presidential candidate to support.
Strawn said voters are focused on finding a GOP nominee who will be able to beat President Barack Obama.
"This level of fluidity has been unprecedented that we've seen throughout the caucus season," Strawn said from his Des Moines office. "And I think that goes to how serious Republicans take the responsibility of replacing Barack Obama. We want to get the decision right."
Strawn added that he expects many Iowans to remain undecided until the last minute.
"Right now, still 2 out of 5 caucus goers are saying they're going to make their minds up caucus night, which is why it's so important for these campaigns to be organized," he said.
Strawn said that while it's hard to predict voter turnout, he's confident there will be a strong turnout Tuesday night.
