U.S. Sen. Chuck Grassley has a comfortable lead over all three of his potential Democratic opponents, according to the latest Rasmussen poll.
The statewide telephone survey of 500 likely voters was conducted Tuesday and has a margin of error of plus or minus 4.5 percent.
Grassley beats out Des Moines attorney Roxanne Conlin, considered by many to be the Democratic primary front runner, by 28 percentage points, 59 to 31. He bests former state Sen. Tom Fiegen 61 to 25 and former state Rep. Bob Krause 59 to 26.
From Rasmussen:
Male and female voters both favor Grassley by wide margins over his three opponents.
Conlin performs best among Democratic voters, but all three Democrats lose anywhere from 22% to 30% of their own party’s vote to Grassley. The Republican carries voters not affiliated with either party by more than 35 points against any of the Democrats.
Grassley is viewed very favorably by 32% and very unfavorably by just 14%.
Three percent (3%) have a very favorable opinion of Krause, while seven percent (7%) regard him very unfavorably.
For Conlin, very favorables are 12% and very unfavorables are 21%.
Four percent (4%) view Fiegen very favorably, and 14% have an unfavorable view of him.
The numbers don’t differ much with a Des Moines Register Iowa Poll released in November that found Grassley beat Conlin 57 to 30. That poll found Grassley’s overall approval rating to be 57 percent, down from 75 percent at the beginning of 2009.
