IA/NV may have been seen as "underwhelming" wins for Clinton at the time, but after seeing all these other caucuses results with Sanders winning by 20-60 point margins, I have a newfound respect for the campaign's strength in these two states.
No idea, but it was definitely robust given the circumstances. She needed a win in these two states to stay alive. Clinton did not contest UT or ID. She did not spend money there or visited the states. Sanders did and he won ID by margin 5-points less than Obama. Can't make a comparison in UT given it was a primary in 2008. But he also outspent her 2-1 in Arizona and spent much more time in the state than her and he lost it by 18-points compared to the 8-point margin in 2008. He should be happy he netted more delegates than expected, but this does not bode well for the larger more favorable Clinton states.
