What about the party that held it's convention in Cleveland?
If we're gonna get symbolic and let that symbolism predict the election... then basically the Democrats (the Chicago Cubs in blue) took the game to the GOP and beat them.
The Democrats held their convention in Philly, the Phillies (71-91) didn't make the playoffs.
If we separate the candidates from the conventions, than you could argue that the WS winning Cubs (103-58) represent Clinton, but Donald Trump wouldn't be represented by the Cleveland Indians, he's a Bronx Bombers fan. The Yankees didn't make the playoffs this year, reaching a reg. season record of 84-78.
The Cleveland Indians are not the GOP. Don't compare our sports teams to Donald Trump, unless it's the Browns.
