Obama's Final State of the Union: 'Speaking to History'

President Obama gives his final State of the Union address at 9pm EST on Tuesday. Here's a guide of expected themes and things to watch:

• Don't expect a laundry list of goals. Instead, expect a "central theme of optimism" that lays out a bigger picture for America, reports the Los Angeles Times.
• This one "is all about his legacy," notes the Washington Post. "He will be speaking to history."
• The speech will be streamed on Amazon Video as a reflection of changing times, notes Re/code. It will also be on YouTube, and Gizmodo has a guide for following along on social media, even Snapchat. The chief digital officer at the White House lays out the thinking here.

• The Hill has a list of things to watch for, including a rebuttal of Donald Trump's vision of America. CNN also has a guide, expecting Obama to try to do a better job of reassuring Americans worried about terror attacks.
• The New York Times and Politico separately assess how Obama has done in his previous State of the Union proposals.
• Those same sites also look back at Michelle Obama's guests for the speech. Times here and Politico here. (And here's a look at Tuesday night's guests.)
• Previous speeches are now available with additional notes, photos, and video via the annotation platform Genius, notes Wired.
