K ima adress the 2 important P's.
For Bernie? I honestly think thats untrue. Not the over 50's vote part, he's unlikely to score a full victory in that to be sure. Everything else though reads like what Republicans think he says vs what he's actually said.
No, this is literally stuff that he is on camera flat out saying; without any editing needed.
Alot of his core policies have become democratic core policies (EC reform and Medicare for All in particular), the latter of which is even popular across parties. Bernie also has popularity in, well, to put it simply when one looks at a donation map you have to take out Bernie to get everyone elses donations in. Man has a base and can use them. For broader popularity though, he does well in the Rust belt compared to other D candidates and also in New England, and is the 2nd choice generally for all other D candidate voters. Even to my surprise Biden voters.
Medicare for All polls well until you tell people that private insurance is going to be outlawed and their taxes are going to more than double to pay for it. Come the General, Trump is going to use Medicare for All to crucify any Dem who doesn't walk it back hard.
He can win, if the party lets him, which is a whole other game.
No, he really can't. This is a man who couldn't even make Hillary fight for it in a primary (she crushed him utterly). Trump will spend the entire campaign trail calling him Comrade Bernie and hammering that point home. His attack ads in Florida will be nothing but Bernie saying bread lines are good, praising Castro, and praising Chavez. That puts the state well out of his reach.
He will be portrayed as an old white dude who promises urban blacks nothing; they won't get out and vote for him.
As for Trump, Judicial picks and abortion are excellent in the south, he's doing a great job at sureing up the Evangelical voter base.
But he doesn't need the south, he's always been going to win the south. What Trump needs is the midwest, the area currently getting throughly screwed by his trade war, and if a recession hits will be screwed beyond belief, that he only narrowly won in the previous GE, and didn't even win the popular vote for.
If the above changes things might look good for old Orange, at the moment though i'm willing to role the dice.
Judicial picks and abortion play well
everywhere except the urban areas. Trump did not become President thanks to the South, he became President thanks to the Amish.
Rural America is going to stick with him, even the people most screwed by his trade war. Not because they particularly like his trade policy but because on the issues that they truly care about the Dem positions are seen as anathema.
The Dem's are running towards their base, Trump is running away from his. Why? Because Trump doesn't need to do anything to turn out his base, the Democrats are doing that for him. He's not even trying to win over independents or swing voters, what Trump is trying to do is get potential Democrat voters to stay home come election day.
