Look - I'm not saying never impeach - the "Now what?" was more asking, "What is the actual plan after the Senate puts him on trial, finds him not guilty, and then attempts to take a victory lap" ?? Since we know that's what will happen, you can't just say "IMPEACH" without an actual plan in place. They need to be more politically savvy than that.
Okay, that's fine.
First, I think that any "moderates" in the Senate can and should be pressured in their states if and when the House considers impeachment. If Indivisible can go for them at town halls over ACA repeal, let these senators hear from people who don't want to be governed by a criminal. Even if a two-thirds majority isn't possible, imagine the horrid damage to the Trump administration if a majority of the Senate buckles and votes to convict. If the darlings vote the wrong way? Then the Blue challenger should go no-holds barred: they voted for a liar and a thief and should be considered guilty at the ballot box. Call them traitors and co-conspirators.
Every single piece of evidence and testimony from a subpoenaed Trump aide can be aired or put on YouTube. Every time they denied an order from the president because they thought the president was ordering something illegal. Every time Sarah Sanders has to say she fucking lied at a press conference and has no basis in reality, under oath. Every time a co-conspirator doesn't remember why he deleted texts asked for by the Special Counsel.
And I think the 2020 manifesto is pretty easy. Sure, talk about M4A. Talk about the environment, inequality, justice reform. All that. But the core is clear - we can't survive a justice system that lets a president bully and lie to us. We can't survive a Republican Party that forgot its reason to exist and aids acts of injustice and theft. This government is Donald Trump fucking stealing from us EVERY DAY and now we know how. He's corrupt. He's a hoe. He's a casual traitor. The Republicans are too because they'll tolerate ANYTHING.
Remember that a lot of voters wanted a Democrat BECAUSE they think Trump is a criminal and want someone to stand up to him. If the Democrats follow Hoyer's lead, and they stand for nothing, then they have no authority to govern and no right to ask for my vote again. That's also supposed to be the core of the Democratic message: "we believe in truth, justice and the American way" and the Republicans don't. The alternative is a Republican Party that's feckless and a Democratic Party that's gutless.
Wanna play for time? Then a clear roadmap at least needs to come from Team Blue: "we're subpoenaing for the full report, we're subpoenaing the AG for lying his ass off, and we're not ASKING Mueller, we're ordering him to fill in the blanks. We're done asking and we're done fucking around and you can call us whatever you want. And we will not rule out impeachment."
