First , some new car pictures : I went to the Obama rally today in downtown Minneapolis ( scheduled at the same time as a nearby McCain / Palin campaign stop ) . I got a free sign and a button upon my arrival . The crowd was just starting to trickle in when I arrived but soon the plaza filled up -- estimates were at 3500 people .

Choices: -- None of the above choices .; -- They 're going to church; -- They 're going to work; -- Candidates are running for president;
Q: Why was there a rally ?
Candidates are running for president
