Read the following context and answer the question.
Context: I went to the Biden / Obama rally in Fredericksburg last night , and thank goodness I knew where to find a hidden parking spot behind the local SPCA . There were a few people with McCain signs on the corners around the University , but after a while they disappeared because there was literally no place on the sidewalks left for them to stand . We were rained on intermittently , but ... so what .
Question: What shows I 'm a big supporter of Obama and Biden ?
Answer:


The fact that I did n't care about being rained on at the rally shows I 'm a big supporter .
