In the olden days, political seasons and Christmas season had no variance as both seasons were seen as festivities and exchange of pleasantries.
When you say political season, I don't think these guys who run the show have a season of doing their stuff. To me politics has no season and the politicians do their thing every day as long as they are on the receiving end which is good business to them...
Actually, I have seen people from the United States commenting how actually they are quite disengaged with politics, expect when there is an important election ahead and they need to figure who they are going to choose to vote for. There seems to be an important percentage of the population of that country who does not actually follow politics, they only start to care when it is "election season" and they get all the political news shoved down their throats by the media machinery of both the political left and the political right.
Keeping this points aside, I find that comparison between Christmas and Politics to be quite out of place, the first one is a holiday, supposed to be festive and bring peace and calmest to those who celebrate it, election season is about ideas colliding figuring out the best way to steer the country with no collateral damage, there is nothing holy or festive about it, at all. They both sound almost as incompatible from one another .
I think I agree with you, OP is not suppose to use those two as comparison because the Christmas part is a period where everyone put a stop to whatever activities they are engaged to and feel relaxed, have enjoyable time with family but that never stops politicians from doing their thing like I said. Politics is like the air we breathe in everyday to politicians, any day they miss out on any activity is like they have missed something big in life so they're always on the move, like a non stop train.
To me those who run the political affairs don't value the Christmas period you talk about, we shouldn't mind what they want us to believe on TV. If they do, what stops them from crediting all the workers or do something special every Xmas season? Politics has this greedy virus that's always on the minds of the politicians so they don't value Christmas.
