As a bit of an exercise in tedium, I've parsed each state's delegate selection plan to acquire the number of delegates in each allocation category. There are actually 57 regions which are apportioned delegates; the 50 states and DC are listed below. Of the additional 6, five are US territories; American Samoa, Guam, Northern Marianas, Puerto Rico and the Virgin Island. The sixth is called Democrats Abroad. These 6 regions will account for roughly 120 total delegates.
Each region's delegates are divided into two groups, pledged and unpledged. This distinction is simple, pledged delegates are bound to a particular candidate in proportion to that candidate's support. The exact method of apportionment is decided by the state parties; in a primary for example, it's generally the raw popular vote.
The unpledged delegates, commonly referred to as super delegates, are allocated to prominent elected or otherwise significant members of the Democratic Party. Much is often made of Hillary Clinton's significant super delegate lead, but the super delegation is very unlikely to overturn the outcome of the pledged delegates.
The pledged delegates are then divided into three further groups; district, at-large and Party Leaders & Elected Officials (PLEO).
The district level delegates are bound to the outcome of a congressional district. District delegates are initially selected at the precinct level, then depending on the state, there is another tier at the county and finally at the congressional level. The table below lists the number of districts in each region; they are the same districts used for the House of Representatives, except DC, which gets 2 for some reason. Each district has their own number of delegates; it is not uniform.
The at-large delegates are generally tied to the overall state level vote; in a primary the raw vote, and in a caucus the district delegates typically select the at-large delegates. The PLEO delegates are also selected in the same fashion as the at-large delegates, but the PLEO delegates are themselves elected officials in the state who self-nominate.
The multiple tiers of delegates makes counting which candidate won which number of delegates difficult. Results reported in the media are all estimates right now as no statewide delegates have actually been selected. The DNC has laid out a common set of rules, such as the 15% viability threshold, but each state can make their own additional rules so long as the DNC criteria is respected.
The table below lists each state by election type and date with a link to the delegate selection plan. The delegate selection plans change overtime and are often amended before official confirmation. As an example, the Iowa plan was amended in August of 2015 where their total delegate allocation dropped from 54 to the current 52. I suspect this has happened in other states and the results are not publicly available or the links haven't been updated.
Super Tuesday is tomorrow, which allocates 837 pledged delegates (plus American Somoa), which is about 22% of the total pledged delegates. I'll post the final polling projections for each state if time allows tomorrow, but Clinton is generally expected to win, Alabama, Arkansas, Georgia, Tennessee, Texas and Virginia while Bernie is expected to win Colorado, Minnesota and Vermont. Oklahoma and Massachusetts are much closer without a clear front-runner.
And a final reminder to report your precinct results if you participate in the Colorado caucus tomorrow.
Update [March 20]: The Michigan delegates were updated to reflect the final apportionment; a draft version was used previously. The election type used in Utah was updated to correctly state that a caucus is used instead of a primary.
