Open Convention?

When will a political pundit start talking about the 1964 film, The Best Man?

Premise of the film is that Fonda and Robertson are deadlocked going into the convention. Both candidates have liabilities. Deals are attempted and in the dramatic conclusion ........ sorry don't want to spoil it for you!

Saw the films eons ago. Can't find it on Netflix or on iTunes. Probably have to go to the library to find it. 

Will see if this is the year, more than 1 ballot is needed to determine the nominee. The last time that happened was in 1948 for the Republicans and 1952 for the Democrats
