Looks good for Trump. In Pennsylvania I’ve read from many sources that the majority of delegates go to the convention unbound even on first ballot regardless of who wins the votes. If true, voting there seems like an exercise in futility.
You are right about PA having most of their delegates unbound but I think a strong Trump victory there next week will help make up some minds at convention time. So I think it’s important for Trump to have a decisive victory in PA.
We vote for the delegates by name, so it’s as democratic as it gets. The one in my district who’s backing Cruz won as a delegate in 2012 too. More power to him this time!
