Primary season always brings out the more extremes in the party, so just because there were more doesn't mean there will be more come general election. And if that is the case, then Trump will also be aided by that as he had extremely high turnout for an incumbant compared to Obama and Bush at least in Iowa (haven't checked NH or Nev yet).

Also, while Bernie appeals to typically non voting youths, he is very unappealing to typically voting elderly or middle aged people. So much so that that many of them will vote for third party, not at all, or Trump. If you go after one demographic you tend to alienate at least another one.

Option 2 is all wrong. Bernie has the most support among independents and non voters and the democratic base. In Nevada, he won among democrats that call themselves conservative and moderate. He won almost every demographic except he was 2nd among old African Americans. He constantly beats trump nationaly in polls and the only one who beats trump in many key swing states and beats him by the widest margin. People don't want a vanilla candidate. Biden, Bloomberg, Pete, Klaubaucher are Hillary Clinton and Clinton is Romney and Romney is Kerry and Kerry is Al Gore. History has shown us that those that excite the base and bring out the most people from the 40% non voters win the presidency. And Bill Clinton, bush, Obama and trump did that. And Bernie is doing it as well. 

Bernie is the most electable. The dems don't need republican votes to beat trump, they just need to excite their own base and make sure young people and non voters come to support them. The people who vote republican will either stay home or vote republican and the people who always bite democrat will vote for any dem candidate regardless. The people who don't do that are the ones that make the difference and if voter turn out is one, trump wins. Bernie brings in the voters. Pandering to the center made the democrats loose a 1000 seats and both houses and the presidency. If the ultimate moderate Clinton didn't win, what makes you think any of the others will? It's like banging your head against the wall over and over again and expecting a different result.

Bernie is not too far left. He is the most liked, most trusted candidate and right now, the most popular. People support his policies. This myth that you should pander to the center needs to die because this has driven the democratic party to the right so much that they are basically the centre right party. And it's why republicans keep winning again and again. 

It all depends on what happens tomorrow.  If Biden does well tomorrow the money will start coming in.  There plenty of big money Donner's that once it clear it between Sanders and Biden will start pouring there money in.

Well, those vote mostly Republican anyway. It's on the fence with Xers (about 50:50), but Boomers and Silent have a much higher tendency to vote republican than democrat anyway. So having a candidate that caters to those people but leaves out the younger ones will just result into those not voting or even worse voting for Trump or third party out of spite. Either way there will be some left out. But are you rather willing to leave those out who would mostly vote for you but turn out in lesser numbers or those who risk voting for the republicans anyway but come in greater numbers?

Also, have a look at the voting charts of the midterm elections in 2018. The amount of boomers voting is constantly dropping, and by now the Xers, Millenials and Zees  are turning out more numerous as the boomers at the polls. In other words, running after the boomers is a lost case anyway on the medium to long term, so better not scorn the younger ones beforehand.

It being reported on cnn that amy klobuchar droping out of the race and will do a joint endorecment with Buttigieg of biden.

Even if Bloomberg were to back out now and do the same for Biden I think it would be contested. If the Socialist delegate count is slightly higher or about equal to the Democrats, I think the Democrats will win the nomination for the Democratic Party in the second round.

Only way I see the Socialists winning the Democratic nomination is if they both crush the Democrats on Super Tuesday.

Democratic Socialist is a mouthful and I'd imagine to most Americans they couldn't distinguish the two if their ideas were on a T chart. In any case, I can't use liberals and moderates now, because the moderates have become liberal and the liberals have become ultra liberal. 

Republican party has swung hard right with Tea Party and Trump with the judges. Democrats have swung far left with Green New Deal. There aren't really moderates represented anymore.

Neiher Warren or Sanders are Socialists period, neither one of them want to nationalize any major industries.
