Pennsylvania: An analysis.

[argentarius]

So voters have to know about the delegates they vote for? What's wrong with just voting for a Romney slate, or a Santorum slate, for instance?

Nothing, but it won't be well advertized. 

Bingo

Again, there isn't a distinction on the ballot as to who the delegate candidate supports for President even if the candidate is publicly known to be for X.

Still thinking of voting for that Paulite friend of yours?
