While watching the Astros take on the Nationals the past few days in Washington, D.C. I learned that there are different caps worn based on political affiliation. The Nationals' cap is red with a "W" for Washington. Republicans and supporters of President Bush wear the regular red cap with the "W" as "W" was a symbol for the Bush campaign in 2004. Democrats and opponents of the Bush administration wear a black cap with "DC" on it.
