This isn’t new news. It’s 28 to 28 in LA even though Trump beat Cruzlose. And Trump tied Cruz 14 to 14 in Alaska when Rube left, which came later after the 15th when Rube badly lost Florida.
You need to work on your math skill. LA only has 46 delegates. It WAS 18 for Trump, 18 for Cruz, 5 for Rubio and 5 uncommitted. According to the article, the 5 Rubio delegate slots are now uncommitted and were filled with Cruz supporters, as were the "unbound" delegate slots. So that means that LA wound up with Cruz 28, Trump 18.
