The only State Trump hasn't taken any delegates in is Utah.
From FiveThirtyEight: 739 delegates.
Which in no way alters the fact that so far Trump has received 37% of the votes cast, netting him a total of 48% of the delegates awarded, and that in order to get the nomination Trump has to win at least 53% of the 944 remaining delegates, which is much better than he has done so far in the campaign when there were more candidates splitting the vote and a 37% plurality was enough to win all of the delegates in a winner takes all state.
