On the call with the campaign today they said they were expecting a "decent" placing, with the "gold standard" being "1st - 5th". The numbers they put forth in the call were: expect about 120,000 to turn out (not counting weather, of course), with 20,000+ votes to place in top two, 15,000-20,000 for 3rd.
I'm thinking that they expect close to 30,000 votes, hence the campaign is now pushing to regain Ron's supporters. You see that with the introduction of Ron making calls, the attack on Cruz lately, and a "special guest" to appear in Iowa near the end of the month (which is probably Ron). Cruz might have videos, but we have the real thing. I remarked that it's a checkmate move by Rand. If you look at his strategy, he spent a year attracting non-Ron supporters, now he's calling the liberty vote home.
If Rand wins Iowa, it's going to be a landslide that's going to sweep the early states. Good news is also coming out of NV, too. Not sure that the status of SC is, but remember this:
Worst case scenario is 3rd, by all estimates.
