Citizens United mounts stealth, last-minute robocall assault in Iowa District 18 even bigger than NOM's; features Mike Huckabee

Although the National Organization for Marriage is making 23,683 robocalls to defeat Liz Mathis in a hotly-contest Iowa District 18 special election (which they have tried to turn into a gay marriage referendum), Citizens United is doing them one better, making 12,000 more calls than NOM did in a last ditch, stealth (until election eve) effort documented by the Des Moines Register.
Mike Huckabee read the script, which was as follows:

Hi, this is former Governor Mike Huckabee calling for Citizens United Political Victory Fund to urge you to vote for Republican Cindy Golding on Tuesday for State Senate to represent you and the other fine folks there in the 18th District.
     With Cindy Golding in Des Moines, Republicans will wrestle control away from the big spending Democrats and put us one step closer to getting our fiscal House in order and most importantly to start getting Iowans working again.
     With our economy struggling to get back on track, now more than ever America, and especially Iowa, needs a problem solver in government- not another celebrity!
     And there’s only one real problem solver and job creator in the race [AKSARBENT: This is a flat-out lie of Huckabee's, since Mathis and her husband employ more Iowans than do the Goldings] to be your next state senator and that is Republican Cindy Golding- that’s why I urge you to vote Cindy Golding…Republican for state senate.

Update: Turns out, Citizens United wasn't the only organization unleashing a barrage of last-minute robocalls. CBS 2 reported on another, very sleazy election eve attack:

The caller says the message is sponsored by the Citizens for Honesty and Sound Marriage in Iowa and it targets Liz Mathis and her stance on same-sex marriage. The calls come in as private and cannot be traced or called back. Monday night the Golding campaign quick to say the message didn't come from them or the Republican party.
