I had to do the following to get this working:

• install scikit-learn (http://scikit-learn.org/stable/install.html)
• install nltk (http://www.nltk.org/install.html)
• download data set: http://www.cs.cornell.edu/home/llee/data/convote.html
• put data set in convote_v1.1/
• fix the path in demo.py to point to the data set (you might have to change backslash to forward slash depending on your environment)
