Headlights On The Parade

My first impression of these two pictures, from the West Des Moines Independence Days Parade - via the Iowa Republican, is that one candidate for U.S. Senate comes across as an elitist who needs to be chauffeured (Rozanne, err Taxanne Conlin).

The other candidate, Charles Grassley, is about 11 years her senior and is still able to walk the route amongst the people.

And the scientific community is united in that fact.
