Environmental signaling derailed the national party in Kentucky and West Virginia, two states where Clinton had no problems in the 90s. So get rid of that part of the platform, and you probably have a better shot there.
Cool it on the social issues. For one thing, just poll current Southern Democrats on these issues (a majority of these voters are African American) and you will see that there is true dissonance between the party in Washington and its voters, to a degree much larger than that of the Republicans even. It was not a winning issue, and Bush really made hay of it in 2000 and 2004 in places like Tennessee, Louisiana, and Arkansas, states that went for Clinton in the 90s.
I think these issues, however, are fundamental to the liberal technocratic West Wing fandom crowd who've run the Democratic Party at an institutional level really since Clinton went away, so its going to be tough.
So, yeah, that should help. A more protectionist trade platform should help in places like Missouri and Louisiana, as well.
