Between the lines on Trump's upcoming Cuba announcement

With President Trump planning to fly to Miami on Friday to announce a Cuba policy that at least partly reverses President Obama's openings for commerce and travel after a half-century standoff, we asked officials inside and outside the White House to help us read between the lines:

• The base loves a little Obama-appeasement rhetoric, and Trump plans to give it to 'em.
• This was a campaign promise that won Trump some vital South Florida endorsements at a crucial time.
• This is a chance for Trump to project personal and national strength.
• It's a reminder the president can do consequential, historic things without Congress. But if you're Obama, it's also a reminder that such changes can be fleeting.
• Big win for Sen. Marco Rubio (R-Fla.), who tutored Trump on the issue (including in debates), and kept prodding for this announcement. Look for Rubio at Trump's event.

L.A. Times lead story, "Trump plans a reversal on ties with Cuba," by Tracy Wilkinson: "The move will be controversial. It could dull a boom in tourism by Americans to Cuba and hurt a burgeoning cottage industry of private enterprise on the socialist-ruled island. And it could allow Russia and China to more easily step in to fill the void."

• "Some Trump supporters argue however that President Raul Castro has failed to improve human rights or expand political freedoms and does not deserve better relations with the U.S."
