I’m debating how much faith to put in the ARG poll putting Huckabee within two of Romney in Iowa.

Most polls have shown the gap closing recently, with Huck in the neighborhood of 19-21-15-19-13 percent, and Romney at 30-27-31-37-26 percent.

I think I want to see if there’s a similar trend in subsequent polls. I don’t have a hard time buying that Huckabee’s gaining ground – the former Arkansas Governor’s practically living in Iowa right now – but I don’t know if a lead that is 11 percent, 6 percent, 16 percent and 8 percent in the four preceding ones almost disappears overnight – at least not without some big news trigger.
