Changing The Presidential Election with R in the Browser

What would happen if different states had a different number of votes?

I never dreamed that I would be able to answer my own question by live R coding in the browser in an Ipython style notebook.  I felt like I needed a screencast to prove it.  Here is the short version.

 

 

Here is the extended version with director commentary (in type).
