I love the saying "Politics is show business for ugly people" because it's pretty much true. Watching some behind the scenes in various documentaries and such, the parallels between politicians and show business acts are very similar. Both are back stage getting prepped up to go out and perform in front of cheering crowds. When they hit the stage, the crowd goes wild. Both have to get a quick briefing on the current location and such. "How are you guys in Cleveland doing tonight?!" Politicians pretty much mimic professional wrestlers, kind of like when Ric Flair would brag about himself and hurl negatives out to his enemy Dusty Rhodes and vice vera. Although Ric Flair and Dusty Rhodes were "enemies", they both worked for the same wrestling federation, the NWA (National Wrestling Alliance).
Like in football, you have fans of the Cowboys and fans of the Redskins. When fans of the two teams enter arguments with each other, each side dismisses most of what the others say. For example, the Cowboys fans say "you guys are very weak in this area". While it is true, some Redskins fans deflect and argue it against it. Then the Redskins fan points out a weakness on the Cowboys. Even though it's true, the Cowboys fan will ignore, deny or make excuses for it. When it comes to politics, most who are interested in it act like homers for their party. While homerism is fine and dandy in regards to sports, the country needs less homerism among the voters.
Just like in sport shows such as "Around the Horn", politics have their group panels on Sunday mornings and on cable news, where you have three or four different guests talking about politics. Half the panel thinks candidate A did bad, while the other half of the panel thinks candidate A did good. The only difference between "Around the Horn" and "This Week with George Stephanopoulos" is the guests on "Around the Horn" get points for their answers lol.
