IA-Sen: Rasmussen finds Grassley lead shrinking

The latest Rasmussen Iowa poll shows five-term incumbent Senator Chuck Grassley still over 50 percent against all Democratic challengers, but with a smaller lead than he had earlier in the year. Rasmussen surveyed 500 likely Iowa voters on April 29, giving a margin of error of plus or minus 4.5 percent.

Survey questions and toplines are here.

Roxanne Conlin is the Democrat who gives Grassley the narrowest lead, 53 percent to 40 percent. Grassley led Conlin 55-36 in Rasmussen’s previous Iowa poll, taken in mid-March. Rasmussen’s summary notes that Grassley “now leads Conlin by only five points among women.”

Many politically active Iowa Democrats believe Conlin can help Governor Chet Culver and our down-ticket candidates if she motivates high turnout among women. I also know many women who plan to volunteer for Conlin’s campaign. She has already held campaign events in all 99 Iowa counties.

Grassley leads Democrat Bob Krause by 57 percent to 31 percent, the same as in Rasmussen’s March poll. He leads Tom Fiegen by 57 percent to 30 percent, a slightly smaller margin than his 57-28 lead in March.

This race is still Grassley’s to lose; Rasmussen finds 63 percent of respondents have a very or somewhat favorable opinion of the incumbent, while only 34 percent have a very or somewhat unfavorable opinion. The corresponding numbers for Conlin are 44 favorable/30 unfavorable.

However, a few stumbles by Grassley could make this race highly competitive in a hurry. At the very least Conlin is going to make it a lot closer than any other Democrat has against Grassley in the last 25 years.

I expect Conlin to have little trouble winning the Democratic primary on June 8. Not only is she the best-known candidate, she out-raised Grassley in the first quarter and had about $1 million cash on hand as of March 31. According to FEC reports, Krause had $352 and Fiegen had $582 on hand at the end of the first quarter.

UPDATE: Rasmussen’s numbers on the governor’s race continue to point to a tough road ahead for Governor Chet Culver. He trails former Governor Terry Branstad 53 percent to 38 percent, little changed from Branstad’s 52-36 lead in Rasmussen’s March poll. Bob Vander Plaats leads Culver 45-41 in the new poll, up from a 42-40 lead in the March poll. Culver is barely ahead of Rod Roberts in the new poll, 43-41, little changed from the 40-38 lead Culver had against Roberts in the previous poll.

It’s not encouraging for an incumbent to be stuck around 40 percent against all challengers. Culver needs to bring up his own numbers and get out there to tell voters about his administration’s successes. For a preview of the case Culver will make with Iowa voters, watch his appearance on Chuck Todd’s MSNBC program last week.

Assuming Branstad will be the Republican nominee, Culver’s campaign will have to take him on aggressively. The race is bound to tighten up, but as long as Branstad is polling above 50 percent the odds are against Culver. Perhaps the governor can needle Branstad and provoke the same kind of response Vander Plaats got during the second Republican debate.

IA-Sen/IA-Gov: Grassley & Culver Are Both Vulnerable

Research 2000 for Daily Kos (10/12-14, likely voters, no trendlines):

This is the first poll to test Chuck Grassley against a couple of higher-profile names: Christie Vilsack, the wife of former governor (and current Ag. Sec’y) Tom Vilsack, and Roxanne Conlin, former head of the Association of Trial Lawyers of America and 1982 Democratic nominee for governor (she lost 53-47 to none other than Terry Bradstad – we’ll visit with him below). Both Vilsack and Conlin’s names have been tossed around as possible candidates recently, with Conlin refusing to rule out a run and Vilsack openly suggesting she might join the race.

The best news about this poll, though, is that Grassley seems to have a cap of about 51-52% against a field which has room to grow. He does better against state Sen. Tom Fiegen, but only because half the state has no opinion of the latter. All the other three Dem names are in a much closer range in terms of favorables – former state Rep. and longtime public official Bob Krause is actually a bit better-known than Vilsack, and Conlin, it turns out, has the best nums with 44-29 favorables. (Also recall that last December, Grassley only led Tom Vilsack by 48-44 in another R2K poll.)

Hopefully Conlin or Vilsack will get in. Either woman would bring considerable resources to bear – Conlin, thanks to her high profile and network of wealthy lawyers, and Vilsack, due to her strong brand name and powerful political connections. SSP currently pegs this as a “Race to Watch,” but if we get a top-tier challenger, that rating might soon change. (Discussion is also underfoot in this diary.)

How frustrating – Gov. Chet Culver utterly swamps a couple of unknown candidates, but along comes former four-term Gov. Terry Branstad showing the incumbent in a very vulnerable position. Branstad is still in “exploratory phase” – he just resigned as president of Des Moines University on Friday, but hasn’t officially announced a run yet. Lingering unhappiness over events from his long tenure, as well as a possible right-wing vs. establishment split, could pose some roadblocks for Branstad. But right now, Culver ought to be very concerned.

SSP currently rates this race a Tossup. (More on this poll in this diary.)
