It’s unclear why Obama chose this moment to issue the call to vote, some six months before the 2020 presidential election.

But many people suggested it was in response to Trump’s earlier single-word post referencing his murky “Obamagate” conspiracy theory that alleges Obama in 2016 led attempts to sabotage his incoming administration.

Trump has intensified his attacks on Obama in recent days ― an apparent effort to distract from criticism of his blundering coronavirus response.

Others speculated that Trump’s recent attacks on mail-in voting and his widely criticized handling of the coronavirus pandemic could have prompted Obama’s tweet.

They also noted Obama’s post garnered more than four times the number of “likes” as his successor’s tweet.
