The delegates know, all too well, that Barack Obama edged out Hillary Clinton in the pledged delegate count largely due to his victories in caucus states. Obama won 13 out of 14 caucuses, but only 18 out of 39 primaries. 42% of Obama’s wins were caucus states, 95% of Clinton’s wins were primary states.
The Delegates also know that Hillary Clinton was the popular-vote winner. Obama supporters take issue with that conclusion, complaining that there is no way to count the popular vote turn-out in caucus states.
But it’s no mystery why some of the caucus states, such as Texas and Washington, which also held primaries, saw completely mis-matched results.
