This favors anti-trump because people will just vote for whatever names they recognize, which'll tend to be establishment types sympathetic to #Nevertrump. In Illinois, prominent local officials tended to sign up as Rubio's and Bush's delegate-candidates. Such people will be elected as delegates in Pennsylvania.
Like the vast majority of "unpledged" delegates everywhere this election , they wil be overwhelmingly be lined up aganst Trump regardless of the primary vote's outcome.
The biggest impact from the primary results here will be: a) the media narrtive of either Trump continuing a winning streak of major states (probably), or the downful of Trump if Kasixh upsets Trump after Cruz wins Wisconsin; and b) come Cleveland, an embarrassment to the GOP if Trump does well in PA but winds up getting screwed in the delegate count
