Just how good was the Clinton campaign's ground game in IA/NV?

[RaphaelDLG]

Not, like, the greatest ground game in the history of the Democratic primary or anything, but, as you imply, decidedly good.

Turning out the unions in LV (with help from Reid) was very important.  Iowa should be one of Bernie's best states for many reasons and, though it was early in the cycle, he only managed a "virtual tie."

Clinton has actually done better in caucuses this time around than in 2008, her margin has been 7.7 points better on average.

State/Change from 2008
Iowa: +4.68
Nevada: -0.38
Minnesota: +11.39
Colorado: +15.59
Kansas: +12.72
Nebraska: +21.1
Maine: -9.34
Idaho: +5.53
Average: +7.7

The only states she's done worse in are Nevada (the only caucus she won in 2008) and Maine (in New England, where Sanders has an advantage).

I think Clinton invested a lot more into MN/CO/KS/NE than she did in 2008, which explains how she did so much better.  She basically left Idaho alone, and she only slightly improved as a result.

You should adjust this for the fact that she's clearly much farther ahead of Sanders nationally and was not ahead of Obama
