Fifty-three percent of registered Iowa Democrats say in a new survey they would support Hillary ClintonHillary Diane Rodham ClintonSessions says FBI agent Peter Strzok no longer has his security clearance Melania Trump puzzles with 'I really don't care' jacket Grassley wants to subpoena Comey, Lynch after critical IG report MORE in their presidential caucus ahead of her visit to the state this weekend.  

A CNN-ORC poll released Friday found Clinton far outpaces other potential candidates, a trend that has continued over the past year. 

Fifteen percent said they would back Vice President Biden in the primary. Biden is scheduled to visit the first-in-the-nation caucus state next week, only a few days after Clinton. 

Seven percent would choose Sen. Elizabeth Warren (D-Mass.) in the primary. Sen. Bernie Sanders (D-Vt.), who has also been flirting with a bid, would garner 5 percent. 

In 2008, then-Senator Clinton came in third in Iowa's caucus, behind both Barack Obama and John Edwards, after her campaign team considered abandoning the state altogether.

Hillary and Bill Clinton are slated to attend Democratic Sen. Tom Harkin's (D-Iowa) annual steak fry on Sunday, a proving ground for potential presidential candidates. 

On the Republican side, former Arkansas Gov. Mike Huckabee leads a crowded field of potential primary challengers with 21 percent. The only other Republican that garners double digits is Rep. Paul Ryan (R-Wis.), with 12 percent. 

The poll surveyed 1,013 Iowa residents, including 608 likely voters, from Monday to Wednesday and has an overall margin of error of plus or minus 4 percent.
