From the Associated Press:
The centrist wing of the party has warned for months that a far-left nominee could alienate moderate Republicans and independent voters needed to oust President Donald Trump.
“The average American doesn’t think we have to completely tear down the system and remake it. And I think it’s important for us not to lose sight of that,” Obama said. “There are a lot of persuadable voters and there are a lot of Democrats out there who just want to see things make sense. They just don’t want to see crazy stuff. They want to see things a little more fair, they want to see things a little more just. And how we approach that I think will be important.”
I know Barack Obama and his record quite well. He is the last person to be lecturing any Democrat about promoting crazy ideas. Obama set out to transform America, and he did.
