According to the Press & Sun-Bulletin, New York could be relevant in the GOP primary despite it’s late date:
“… Despite New York’s position at the end of the primary schedule, April 24, New York’s GOP chairs are beginning to think the state’s 95 delegates could mean a lot to candidates … The state’s impact on the race will vary depending on the outcomes of several primaries that are scheduled before it … There will be 15 more primaries or caucuses before New York gets to vote, including Texas, which holds the second-highest number of delegates, 155, and whose primary is tentatively scheduled for April 3. California has the most delegates at stake, with 172, and its primary is June 5. New York has the third most … most GOP leaders think the primary will factor into deciding the party’s candidate, if only because of a change in the system from previous elections. For this year’s primary, New York will no longer be a “winner-take-all” state. Delegates will now be apportioned among candidates on the ballot based on the voting results …”
I haven’t seen any polls yet, but I’d give Mitt Romney the edge in the state by a considerable margin.
