Iowans have started the process of picking the Democratic and Republican presidential nominees for 2016.
Early-arriving voters at Republican caucuses indicated they were deeply unhappy with the way the federal government is working. Four in 10 said they were angry and half said they were dissatisfied. And preliminary entrance polling shows six in 10 Democratic caucus-goers wanted a candidate who would continue President Barack Obama's policies.
The indicators were based on interviews with voters who arrived early to caucus sites across the state, conducted by Edison Research for The Associated Press and the television networks.
While both parties caucus on the same night, they do so with different rules. Republicans vote by private ballot. The state's 30 Republican delegates are awarded proportionally based on the vote.
Iowa has decidedly mixed results in picking eventual nominees. The past two Republican caucus winners -- former Arkansas Gov. Mike Huckabee and former Pennsylvania Sen. Rick Santorum -- faded as the race stretched on. But Barack Obama's unexpected 2008 victory was instrumental in his path to the Democratic nomination.
