There are way more Democrats in the US than there are Republicans, the Republicans just cheat through gerrymandering, voter suppression, and unfair systems like electoral college and 2 senate seats per state.
I don't think Democrats should care what 'appeals to Trump supporters' about him. If anything, Democrats now realise what a lost cause it is to try and reason with a group completely incapable of bipartisanship.
**** them even MORE than ever before.
ETA - trying to understand the deplorables is what's gotten them to this point in the first place. They need to take the gloves off and start punching back.
There are two parts to winning. The first is to offer up a coherent, attractive set of policy alternatives. The Democrats fail here.
The second part is to try to avoid energizing your opponents base. Your mentality fails here.
**** the 40% who support them? Yeah, there's a good idea.
**** nearly half the country because they would rather vote for a braying ass like Trump than a collection of confused, screwed up, disorganized identity politics kooks.
As for 'punching back', you might also want to bear in mind that the 40% you want to say '
**** them' to have almost all the guns, and includes most of the military and police.
