Booker: “I confess that I have been imperfect. I confess that I’ve been inadequate to the moment. I’ve confess that the Democratic Party has made terrible mistakes that gave a lane to this demagogue. I confess we all must look in the mirror and say ‘we will do better.’”
“Toe the line” = conform to standards by lining up with your toes on the line. What the heck would “tow the line” mean as a metaphor?
Like the line is the standard, and you’re pulling it, like you’re in a line of people all pulling on the same line in the same direction.
