Lately, Trump's obsession with 2020 has also led him to indulge unhinged and false notions about being "reinstated" as commander-in-chief, according to three people familiar with these conversations, one of whom said he has been constantly watching the conspiracy-laden TV channel One America News and intensely following an ongoing Republican-demanded audit of votes in Arizona's Maricopa County... Should Trump use his Saturday appearance to deliver a public tirade about 2020, he could hobble GOP efforts to develop a compelling message for the midterm cycle. To prevent that from happening, he has received advice from several corners of his orbit to deliver a forward-looking speech featuring fresh lines of attack against President Joe Biden and bold references to GOP policy priorities. Some Trump allies hope his remarks will serve as a blueprint for Republican candidates seeking to court his supporters on their own between now and next November, while others find the prospect of him focusing on anything but 2020 laughable.
