(CNN) — A new survey asked Iowa voters about potential presidential candidates who’ve already run for the White House, and the results show some good news for Republicans Mike Huckabee and Paul Ryan.

But for Rick Santorum, who won the Iowa GOP caucuses in 2012 by a razor-thin margin, and Rick Perry, the results indicate Hawkeye State Republicans aren’t quite as excited about the prospects of another presidential bid by the former Pennsylvania senator and the Texas governor.

According to the Des Moines Register poll, less than half (48%) of Republicans in the state think it’s a good idea for Santorum to run. Some 30% say it’s a bad idea, while 22% are unsure.

Iowa, which holds the nation’s first nominating contest in presidential election years, was a heavy focus for Santorum in his last presidential run. He traveled to all 99 counties and became the surprise victor of the state’s caucuses.

Santorum battled Mitt Romney far into the 2012 primary calendar but ultimately dropped out in April.

Perry, meanwhile, holds a narrow advantage over Santorum in the new poll. According to the survey, 50% think it’s a good idea for the governor to run again. The 2 percentage point advantage over Santorum falls within the survey’s sampling error.

In the poll, 34% say it would be a bad idea for Perry to get back in the presidential ring, while 16% are unsure.

Perry generated a lot of buzz when he entered the 2012 White House contest, but he finished a disappointing fifth place in the early January caucuses.

After placing last in the New Hampshire primary a week later, he dropped out of the contest, just before the South Carolina primary.

In the survey, 65% of Republicans think it would be a good idea if former Arkansas Gov. Mike Huckabee ran again. The Baptist minister won the Iowa caucuses in 2008.

His surprising Iowa win gave Huckabee the momentum to carry him through the primary process until March, when Sen. John McCain clinched the nomination.

According to the poll, 25% say it would be a bad idea for him to run again, while 10% are unsure.

And 2012 GOP vice presidential nominee Paul Ryan appears to have a lot of support in Iowa – this time for president. Some 67% of Republicans say it would be good for the congressman from Wisconsin to run, while 16% say it would be bad and 17% are unsure.

On the Democratic side, 88% of Democrats want former Secretary of State Hillary Clinton to run again, while 58% say it would be a good idea for Vice President Joe Biden to campaign. Clinton came in third during the 2008 Iowa caucuses, losing to then-Sen. Barack Obama’s big finish. Biden came in fifth place that year, with only 1% of the vote.

The poll was conducted February 23-26, with 703 Iowa adults interviewed. The overall sampling error is 3.7 percentage points.
