Welcome to our live blog of the Democratic National Convention!
For the next three nights, I’ll live blog the Democratic National Convention from 9pm—11pm eastern.
Tonight’s highlights include speeches from First Lady Michelle Obama, San Antonio Mayor Julian Castro, and Chicago Mayor Rahm Emanuel.
Please leave any thoughts in the comments section—I’ll use a few of them for the main thread.
