Well, I guess I don’t mean work exactly, because I assume the actual voting process mirrors Iowa. But why has only the GOP win been announced? (It was Romney) Was it really held today, on a weekend day? More importantly, was the caucus held for Democrats yet? There’s been very little said about Wyoming, so little that no one I’ve talked to even new it had happened until the results came out, so I’m a bit confused.
The Republican Wyoming caucus was, as you said, January 5th. The Democratic primary will be March 8th.
Both the Democrats decided to wait until Tuesday.
Wyoming’s Republicans lost half their delegates as punishment for scheduling their caucus too early for the national party’s taste. The Democratic National Committee is more severe. Had Wyoming Democrats scheduled their caucus for yesterday, the national party would have stripped them of all their delegates, which is what happened to Michigan and Florida.
Romney was widely expected to win the caucus. I believe he was the only candidate that actually campaigned in Wyoming.
Are there any other states that have split caucuses / primaries (that is, the Democaratic and Republican ones are on different dates)?

Good one 
2006 congressional election:
Cubin (R) 93,196 votes
Trauner (D) 92,227
Several states hold two caucuses on different dates: Hawaii, Idaho, and Maine at least. As far as I know, only South Carolina has two primaries on separate dates.
This explains the Wyoming Caucus Process a bit. Its a little different from Iowa, but could be pretty entertaining if you attend.
