23M non-college educated white men and several million Evangelicals did not vote in 2016. Pascale has been working overtime to reach these people and get them registered for 2020. Also, Trump will inevitably gain pocketbook voters for successfully keeping the economy afloat for three years, particularly when the alternative is a man attempting to sell a revolution and a tax overhaul during relatively good times. So it is inaccurate to say that Trump does not have room to expand the tent. He does and what's sad is you guys seem content forfeiting one of the pillars of the 2018 Democratic constituency - white educated women. Bernie is running even w/ Trump for them before spending a dime on anti-Bernie advertisement. If that holds it will be a disaster for Dems in 2020. In the chart below you can see for yourself what the spread was in 2018. Bernie isn't making that up with young and latinX voters, sell that shyt to someone else more naive than me.
The inconvenient truth for you guys is while Bernie will undoubtedly run it up in liberal bastions across the country, the moderates from the '18 class that won in affluent purple districts like the suburbs of Atlanta, Dallas, Southern California, and Western PA will most likely lose if they are anchored to a socialist atop the ticket. If a guy like Colin Aldred, a potential star for the Democratic Party, has to go to the business community in North Dallas and spend time and energy explaining to them why our party's leader wants to force US companies to dilute shareholders and divert profits so that employees own 20% of the company, he will lose. If Conor Lamb has to go to his constituents and tip toe around the fact that our party's leader wants to implement an immediate ban on fracking, he will lose. If Mark Kelly has to explain away why our party's leader wants to not only decriminalize the border but take it a step further and repeal the 1325 stature, he will lose.
I believe Bernie's current high favorables come from the fact that most Americans still think of Bernie as "the independent that took on evil Hillary and got screwed by the party". When they hear about how extreme his policies/views are, suburban voters who voted D in 2018 are going to run back to the GOP faster than you can believe. From a Texas Democrat’s perspective who is hopeful about the possibility of flipping the legislature, I'm not enamored with any of the candidates helping getting this done, I personally support Warren, she shares many of his policy proposals, but I believe there are distinct negative implications running a “socialist” at the top of ticket.
