The 2020 Democratic presidential candidate field seems to grow by the day, increasing the chances that someone unexpected could emerge from the pack.

But, at the moment, the most conventional candidate is ahead in the early polls. That would be former Vice President Joe Biden.

Historically speaking, though, there isn't much recent precedent for someone like Biden to win the presidency, even if he does snag the party's nomination, presidential biographer Jon Meacham Told NBC's Chuck Todd on Sunday's edition of Meet the Press. Meacham, who has written books about Franklin Roosevelt, Andrew Jackson, Thomas Jefferson, and George H.W. Bush, said that when looking at Democrats who have been elected to the Oval Office in the post-World War II era, most of them have been younger, more innovative forces.

"You can't build bridges to the past," Meacham said, arguing that there is a risk Biden will be remembered as this era's Bob Dole, a successful Republican politician who served as the party's Senate leader for over a decade and challenged — before ultimately losing to — former President Bill Clinton in 1996.

That said, Meacham also acknowledged that President Trump defied all expectations to win in 2016, so sometimes you need to throw the history book out the window. Anything can happen. Tim O'Donnell

If you love Keanu Reeves, clear your schedule on May 21, 2021, because Hollywood is treating you to a double feature.

Warner Bros. has announced that The Matrix 4 will arrive in theaters on that date, which also happens to be the date Lionsgate had previously scheduled for the fourth John Wick movie. Honestly: Just cut out the middleman and give us the John Wick vs. Neo movie of our collective dreams. Read more at The Wrap. Scott Meslow

Let's hope Vacation is all you ever wanted, because you're about to get a lot more of it.

The Griswold family — immortalized on the big screen in the movies Vacation, European Vacation, Christmas Vacation, Vegas Vacation, and an Ed Helms-starring reboot you probably forgot about — is bound for the small screen, reports Deadline.

The new TV series, titled The Griswolds, will premiere on the upcoming streaming service HBO Max, and promises to explore the family's "daily lives in the suburbs of modern-day Chicago," because nothing says "Vacation adaptation" like a bunch of people sitting around at home.

The upcoming Game of Thrones prequel spinoff House of the Dragon is set hundreds of years before the events of the original series, which makes it rather unlikely that fan favorites like Tyrion Lannister or Arya Stark will be popping in for cameos.

But one Game of Thrones actor who could actually, plausibly appear in House of the Dragon says she might be down to reprise her role: Carie van Houten, who played the "red witch" Melisandre.

Melisandre was eventually revealed to be very, very old in one of many Game of Thrones plot twists that didn't actually go anywhere — but hey, at least that gives the spinoff something to explore. Read more at Entertainment Weekly. Scott Meslow

Between HBO's Big Little Lies and and Apple TV+'s The Morning Show, Reese Witherspoon has spent much of 2019 on the small screen. But there's one big-screen character she's keen to revive: Elle Woods, the protagonist of 2001's Legally Blonde and its sequel.

A third Legally Blonde hasn't formally been greenlit, but Witherspoon confirmed to The Hollywood Reporter that it's on her list: "We discussed it and thought, maybe it's time to revisit" — and given that the last Legally Blonde movie ended with Elle Woods setting her sights on the White House, the 2020 election could be about to get very interesting.

Everything may be proceeding as some Star Wars fans had foreseen.

A wild new clip from Star Wars: The Rise of Skywalker released Thursday provided one last-minute bombshell reveal from the film, one that very strongly suggests a fan theory surrounding Emperor Palpatine will end up being true.

In the clip, Palpatine, who was thought dead in Return of the Jedi but has somehow returned in The Rise of Skywalker, communicates with Kylo Ren and tells him, "I have been every voice you have ever heard inside your head." The line starts in Palpatine's voice, then morphs into Supreme Leader Snoke's voice, and finally turns into the voice of Darth Vader.

The clip's implication seems to be that Palpatine isn't just suddenly back now but has actually been quietly manipulating Kylo for years. This immediately brings to mind Kylo speaking with Darth Vader's charred helmet in Star Wars: The Force Awakens and asking his grandfather to "show me again. The power of the darkness."

It wouldn't make sense for Anakin Skywalker to show his grandson visions of the darkness considering he turned from the Dark Side before he died. But ever since Palpatine's return was announced for The Rise of Skywalker, some fans speculated he was actually the one behind these visions all along, with Palpatine just tricking Kylo into thinking he was communicating with his grandfather. That certainly appears to be where The Rise of Skywalker is heading.

The addition of the Snoke voice could also imply he was merely a puppet of Palpatine or was even just Palpatine himself, which might explain why Palpatine's theme briefly popped up on Star Wars: The Last Jedi's score during a Snoke scene. Does this mean Palpatine alone was responsible for turning not one, but two members of the Skywalker bloodline to the Dark Side?

We'll find out for sure when The Rise of Skywalker hits theaters on Dec. 20. Brendan Morrow

President Trump's impeachment saga is just begging for an HBO adaptation.

There's foreign intrigue. There are talkative star witnesses. And there's the possibility of seeing Timothée Chalamet squeeze on a bald cap to play Rudy Giuliani once he's a few decades past his prime. All of that — but in the present day and shoved into the Senate floor — is what Trump wants out of his upcoming Senate trial, Politico reports via interviews with eight current and former senior administration officials, Trump campaign aides and Republicans close to the White House.

Trump used to be worried about impeachment, even angry, Politico says. Yet lately, Trump has started laughing the whole thing off, calling the charges against him "flimsy" and the whole thing "impeachment lite." The change in attitude comes as "White House and campaign officials" start to believe "impeachment could become politically advantageous" both for swing-state Republicans and those challenging vulnerable House Democrats, Politico reports. They've gotten their confidence from polling that has shown impeachment is "unpopular with Republicans" and questionable among independents, and also the fact that no Republicans on the Hill have defected to back the process, Politico continues.

But Trump and Senate Republicans aren't on the same page about everything. While the Senate reportedly just wants to get this whole thing over with, Trump "would prefer it become more of a TV spectacle with high-profile witnesses and smooth-talking attorneys to fully exonerate him," Politico writes. After all, an appearance from Alan Dershowitz would make the O.J. Simpson parallels just too much to handle. Kathryn Krawczyk
