Why is the map over the past 5 years? Why not over the last 4 years or the last year or the last 10 years?

I suspect the reason might be because if you go back 6 years places like Massholachusetts which was receiving tremendous amounts of federal highway dollars for the Big Dig would be RED instead of BLUE. It might be interesting to see the maps for each year and for the last N years from N = 1 to N = 10 to see if the map was cherry picked from a number of maps that looked materially different.

I suspect with the Republicans in charge, they have been able to get their states more money. Just like the Dems probably did when they were in charge.
