It probably has more to do with publishing time. The wiki site has been very accurate so far this year, but they may or may not be lagging here.
I trust their integrity so far.
Okay, this morning AP has Trump at 319 and Cruz at 226, a difference of 93.
Politico also has Trump at 319 and Cruz at 226, a difference of 93.
