Sure. Of course you would want to work to advance a good policy, even if it is being implemented by President Trump. But I think that the overall goal of saving American democracy from Trump may come first, at least for the Democrats. This potentially includes an investigation of his campaign’s ties to Russia and his role in the Russian cyberattack on US elections. If the evidence proves what the Democrats suspect, their goal will be to impeach President Trump, potentially convict him of breaking the law and force him to resign. Given that strategy, it becomes harder to believe that they would be at the same time working with him on implementing his policy goals.
