BLUE ON BLUE: Obama may release statement with Sanders climbing the polls.

People close to Obama point out that he has always said that he will support the Democratic nominee, whoever that may be. They also point out that Obama’s opinion of Warren has softened since November, and he is said to be growing comfortable with endorsing her fully if she should win the nomination.

But, these people add, he has recently grown even more wary of Sanders as the Vermont senator appears to be gaining momentum in polls and the Democratic primaries begin to heat up with the Iowa caucuses and the New Hampshire primary both in February.

Obama has told people in private that Sanders is both temperamentally and politically unfit to beat Trump in the 2020 general election, these people say. Among his concerns are Sanders’ strident form of politics and confrontational manners where he was known not to seek compromise during his long years in the US senate. Meanwhile, Obama is said to worry that Sanders’ far-left policies, which include massive tax increases, free college tuition and massive student debt forgiveness, would alienate even traditional Democratic voters.

Bernie Bros thought Obama was too moderate, and don’t seem likely to listen to what he has to say about Sanders.
