Democrat 2020 platform?

So does any democrat candidate have a platform for their 2020 run? So far they all say the same thing. "We must impeach Trump" then their whole rally is a Trump bash fest. Not one mention of what they plan to do for America and it's citizens. Not one viable goal??? At this point Trump is going to win in a landslide! That strategy failed in 2016, and it's going to fail in 2020
