Twitter has ~200m daily active users. I can't find recent churn numbers, but older reports suggest it is quite high[1]. Generally, churn would not have much of an ideological bias. On average people would leave for personal reasons and so you get an even-ish spread. However, if the major events of the day do have an ideological character - you would expect those events to have an outsized impact in one direction or another on people along those ideological lines. So on a normal week you'd see both liberal and conservative accounts get +500 and -500 followers, but on this week the liberal gets -1000 and the conservative gets +1000. Same churn, but driven by what is on peoples' minds.
