If Paul should manage to pull this off, though, it is only in 7 states: IA/CO/MN/ME/WA/MO/NE. Of course, that is a maximum of 237 delegates at stake, plus whatever pittance he wins in other states. Of course, that's over 10% of the delegates, which isn't an insignificant amount.
How are delegates chosen in the other caucus states, like Alaska or North Dakota? Is it similar to how NV does it, proportionally based on the straw vote?
Alaska allocates their delegates proportionally, though the percentage of the Tampa delegates each district convention gets to choose is ordained ahead of time (i.e. differential turnout doesn't matter).
Idaho does a similar system, but has recaucusing at each precinct until someone gets a majority or there are only two candidates left.
Kansas allocates more like Tennessee (proportional to the vote, with a 20% cutoff), so Paul is probably completely screwed here. Hawaii also does it proportionally, but with no cutoff.
North Dakota allocates delegates "in such a way so that they best reflect the presidential preference of the Caucus participants." What that means is up to interpretation, and it's possible that a Paulite junta could interpret that very liberally.
