SEASON FINALE: It’s not unusual for series to end their seasons with cliffhangers, but even The Circus, which ends its fourth season tonight, is doing it – big-time. Donald Trump is poised to enact his first presidential veto, in response to Congress’ rebuke of his declaration of an emergency to divert funding for the border wall.  The Mueller report may be delivered soon (a familiar teasing refrain, but this time it may be more accurate). And more presidential candidate hopefuls on the Democratic side keep entering the fray – including, this week, Beto O’Rourke, with Joe Biden promising a definitive decision any day now. Oh, and Trump’s inner-circle cronies, Paul Manafort and Roger Stone, are in court, and in front of judges, yet again. What a week… and afterward, what a cliffhanger until The Circus reopens for Season 5.
