If it's blockbuster entertainment you're after this holiday season, rely on America to provide it. Regardless of the expected impeachment of Donald Trump in the House of Representatives overnight, the result is a foregone conclusion (the Republican-controlled Senate will not convict).

But for real suspense, there's still Thursday's Democratic Party primary debate. Phantom menace Michael Bloomberg won't be there, but the four skywalkers are all lined up: Darth Joe Biden, Princess Elizabeth Warren, Bernie "may the Force be with you" Sanders, and young Padawan Pete Buttigieg.

Emperor Clinton is nowhere to be seen – for now.

Hillary notwithstanding, the Democratic Party doesn't quite have a dark side and a light side, but it does have two wings. Among its presidential contenders, Biden is the lead candidate of the moderate wing, with the 37-year-old Buttigieg waiting in the, well, wings. Warren and Sanders, meanwhile, appeal mainly to the progressive wing.
