Ohio has voted for the winning president on 28 out of the last 30 US elections. So while using Ohio alone to predict the result is not very scientific it is interesting. Using polling data available on Kaggle I plotted the poll results for the last year or so:
This clearly shows that Clinton's vote(in blue) has fallen away in the last week white Trump has stayed constant. So based on this Trump is about 24 hours away from being elected president of the USA.
