SIOUX CITY | The dust has barely settled on the 2012 presidential campaign, but politicos are already thinking ahead to 2016. President Obama will be leaving office and the two major political parties will have open races to pick a nominee.

U.S. Sen. Marco Rubio, R-Fla., made an appearance just two weeks after the election in Iowa, which has the first caucus in the presidential candidate selection system.

On Dec. 6, Hillary Clinton, the former first lady and a 2008 Democratic candidate, laughed off questions about her interest in the 2016 race.

Repeating an exercise from four years ago, the Journal surveyed Republican and Democratic party leaders from Northwest Iowa to see who they favored in 2016. The results were a mix of old guard candidates and new faces.

Rubio and Clinton emerged as the favorites with the most points after the party leaders gave their top 3 choices. Notably missing, however, was former Florida Gov. Jeb Bush, considered by many national pundits as a GOP frontrunner.

University of Iowa Political Science Professor Tim Hagle said Bush is perceived as "an establishment or too moderate" candidate, which turns off some Republicans.

Hagle he wasn't surprised by the love for Clinton or Rubio.

"(Rubio) is a person who a lot of Republicans feel comfortable with... He is young, but he'll have another four years of experience," Hagle said.

Plymouth County Democratic Party Chairman Jon Neunaber had Clinton as his top pick.

"There are still a lot of people out there, especially women, who would like to see a woman president in their lifetime," said Neunaber.

Ida County Republican Party Chairwoman Rachel Law was one of six party leaders who had Rubio as their top preference, making him the runaway pick.

"I feel he can reach out to a more diverse group of people to get away from the stereotype that republicans have," Law said.

Among Republicans, two men who factored heavily in the 2012 contest came in behind Rubio.

Vice presidential candidate Paul Ryan received  the second most points and former presidential candidate Rick Santorum was third. After those three, there was considerable drop off to candidates such as Chris Christie, Sarah Palin and Michelle Bachmann.

Coming in at second place among Democratic candidates was Elizabeth Warren, the senator-elect from Massachusetts. She was followed by New York Gov. Andrew Cuomo.

"We would have a better chance of winning the White House with a new crop of people," said O'Brien County Democratic Party Chairwoman Kim Weaver.

Northwest Iowa Democrats also liked Maryland Gov. Martin O'Malley, U.S. Sen. Sherrod Brown, D-Ohio, and vice president Joe Biden, although Biden wasn't mentioned as the top choice by any of the respondents. Hagle said he doesn't envision Biden having legs to do well in 2016.

Overall, Democratic leaders named 14 people, while Republicans pointed to 11.

Drake University Political Science Professor Dennis Goldford cautioned observers from putting much stock in the top picks from county party chairs this early in the process.

"This is just rank speculation, based overwhelmingly on name recognition," he said.
