The Democratic Convention spent three days presenting a positive message of America, of themselves, and of the future. This was a clear contrast to the dark, paranoid vision presented by Trump's Republican Convention. The Dems had inspiring speeches by top Democratic politicians, notable civilians, and a former and present president. The Trump convention was notable for an absence of Republican notables and politicians.
Hillary capped it off with a determined, workwomanlike, display of competence, knowledge, and caring. It was a sharp contrast to the dystopian harangue of the Reps.
Hillary's main point is her deep knowledge and a lifelong engagement in the issues both domestic and foreign. She and her party spoke to their commitment to national security, and her primary message was one of caring and compassion. This is the natural home of the Democratic Party - caring.
Her message is that she, and her party, have a lifelong commitment to making people's lives better. That people are not on their own in a cruel world, but rather we can all create better lives by working together, by helping each other, by caring about and for each other. She contrasts that with Mr Trump who offers only tweets and bumper sticker slogans - a man without a clue, and a man without a plan.
Hillary, on the other hand, is full of plans. She could lay them out for 24 straight hours. She laid out a bunch of them in her acceptance speech. That doesn't end up with a big bumper sticker moment to remember her speech by, but the point is still important. Hillary's message is that it takes more than bumper stickers, it takes hard work, caring, compassion, toughness, determination. Her message is her life of service and determination. Her message is that she will work her tail off and get things done to help and protect the American people. She doesn't have soaring rhetoric, she has a lifetime of service and engagement in all aspects of government.
She promised to be a knowledgeable workhorse. Underneath it all is her main message - I am not a flibberty gibbet, and I am not crazy. Which is her real distinction from Donald Trump.
