Although from what I've read, the delegates could get to the convention and vote however the hell they like, most people believe he wonthe most delegates, when his caucus numbers are added to his delegates from the voting process.
The race is closer than I'd like, but seeing as I heard first hand that Republicans were voting for Sen. Clinton in the open Wisconsin Primary, and anecdotally that they were doing it in Texas, I think her numbers could be exaggerated both here and there.
Aha! "Jack Turner" at Jack and Jill Politics posts a comment from a Texan on the ground with a compelling [yes, still anecdotal] story about Clinton votes by Republicans in Dallas.
