WASHINGTON (CNN) - As the presidential campaign season heats up, recent polls taken in Iowa reveal drastic inconsistencies in their results, and show that voters just haven't made up their minds yet.
"Early in the season people aren't paying a lot of attention," CNN Polling Director Keating Holland said. "Polls bounce around a lot when voters' minds aren't made up."
A Washington Post-ABC News Poll released Friday shows Illinois Sen. Barack Obama, former North Carolina Sen. John Edwards and New York Sen. Hillary Clinton virtually tied for first place with roughly 26 percent of the vote.
Other polls taken in the Hawkeye state show more distance between the candidates. An American Research Group Poll puts Clinton ahead of her opponents with 30 percent of the vote, followed by Edwards with 21 percent and Obama with 15 percent. A KCCI-TV poll shows Edwards in the lead with 27 percent, followed by Clinton with 22 percent and Obama with 16 percent.
