You should be asking the Biden campaign. They're setting the strategy.

Right now, in a field of 24 candidates, Biden has somewhere between 35-40% of those polled. That is a commanding lead, this early in the campaign season. We're at the end of a three-day holiday weekend, so folks are not watching so much news just now. They're doing other things, really.

Campaigning costs money and takes energy. Biden is, apparently, saving both right now. As long as his poll numbers hold, there's no real reason to be out campaigning hard at the moment.

Don't worry, though. You'll be seeing plenty of Joe Biden. When he will launch an all-out campaign effort remains to be seen. Meanwhile, all of the candidates who are currently polling in the single digits are feeling the need to be out on the stump as much as possible. Will that help them? Perhaps.

It's early days yet in the Democratic primary campaign season. The list of candidates is probably complete, now. Initial poll results have been pretty stable.

Things will ramp up this summer and fall. Right now, most people are not really thinking hard about the primaries. There's lots of other stuff to do. But, State Fair season is about to start. Schools are letting out for the summer. There will be plenty of campaign opportunities coming up.

Truth be told I’d like to see more of Joe but that’s because I want comforting. I think the campaign is just meting it out and planning to have the message become big and serious in the late summer/early fall. And I think they might be watching the 45 shot show, the Democrats’ response, and planning accordingly behind the scenes.

At least that’s what I’d be doing!

I also would like the “comfort,” but I am sure he knows what he is doing.

...which, while annoying to people interested in policy, is probably Biden’s best move. He can’t wait to work with his Republican friends after their epiphany.

I think you nailed it, but perhaps nobody noticed.

They are not Biden's Campaign Manager?

he's doing. Nobody cares what the folks with minimal support are doing. Even Bernie is having trouble getting anyone to pay attention to him.

Journalists, people who attend fundraising cotillions, they all think their opinions are special.

Seems to me all the candidates constantly holding meetings in Iowa and New Hampshire will wear out their welcomes long before any votes are cast.

...there's a long time to go before this heats up.

such as “fundraising, one-on-one calls, policy development and the building of a campaign infrastructure.”

While the other candidates are out there in public working for votes, Biden assumes he already has them. While the other candidates are out there talking public policies, Biden counts on voters imagining they know what his policies are.

Campaigning is for the little people, that's what that sounds like.

the kind of grueling campaign schedule necessary to win a presidential election - a 78 year old man LIKELY can coast his way to winning re-election to Senate (where he is essentially running unopposed against a sacrificial lamb); he MIGHT be able to coast his way to winning the Democratic presidential nomination against a weak field; but he's NOT going to be able to coast his way to defeating an incumbent president - it's going to be a grueling ordeal and men much younger than Biden have found it to be very tiring. I certainly would like to see some assurances that Biden can still campaign at that level before he's locked in as the nominee.

started. I think it's a smart move. He'll be around and we'll see plenty of him. Some of the candidates I'm sick of already..LOL.

They loved having Dotard call them up all the time and fumed that Hillary wasn't at their beck and call, answering all those "but her emails!!11" questions.

self derailments, his best bet is indeed to lay low.

are supporting Biden has a lot to do with his kind of having the advantages of an incumbent vp even though he is out of office.

he is already a known figure .

the problem for him would be if it gives someone else a chance to convince voters to support them.

doesn't indicate--to me--a lot of confidence in your message. Just sayin'.

By using the logic inferred in your OP, those candidates you mentioned should be thanking Joe Biden. He's giving them the chance for more exposure, and less exposure for him. The Washington Post article reflects more desperation than legitimate criticism.
