They no longer generally release their crosstabs. I do wish I knew if they only pick 'caucus goers' by past attendence, which would discount the fact that only the GOP have a real election this year. Obama drew the independents last year. this year those who caucus will be going for Ron imho.
Whatever. Rasmussen's house effect doesn't like Ron, never has. Where is this next to Rasmussen's LAST poll of Iowa? I'm suspecting it is up, which means Ron's RCP in Iowa goes up, but I haven't checked.
Ron's internal polling was like Bloomberg/Des Moines Register's though, and he uses the same company Rand used for internal polls. I'm believing those. Des Moines Register's polling company (which Bloomberg used) is considered the gold standard of polling for the Iowa caucus.
