Republican presidential candidates' entourage size comparison

The New York Times created this neat little graphic.  Here is the full version.  Iowa results are at the bottom of this post.  As you can see, the size of the entourage has no correlation whatsoever with how many votes are garnered.

2012 Iowa Caucus results:
1. Romney 30,015 votes 24.6%
2. Santorum 30,007 votes 24.5%
3. Paul 26,219 votes 21.4%
4. Gingrich 16,251 votes 13.3%
5. Perry 12,604 10.3%
6. Bachmann 6,073 5% (She dropped out today.)
7. Huntsman 745 votes 0.6%
