Here are some numbers:

Total Iowa Registered Republicans as of 1/14/16 = 1,046,955
- per Iowa Secretary of State website

(The 2012 total Republican caucus vote was 121,255).

These are the possible turnout results for 2016:

If 120,000 turn out, that = 11.4% turnout

If 140,000 turn out, that = 13.3%

If 160,000 turn out, that = 15.2%

If 180,000 turn out, that = 17.1%

If 200,000 turn out, that = 19.1%

It is entirely possible that 160,000 will turn out this year, just a one-third increase over 2012, and still just 15.2% of total registered Republicans.

Add to that the number of party-switchers who will also caucus Monday evening and the results could well be YUGE!

Aha. Good point.

Trump gets 30+% of 160,000 votes in Iowa. Wonder how much it costs per vote?

If I may question your numbers, the 120,000 caucus goers included party-switchers.

And, that year, the Dem candidate was uncontested -- while this year it will be hotly contested.

Consequently, there will likely be fewer cross-overs than in the past.

There are not 1 million plus registered Republicans in Iowa. Not even close.
