If your life was not great, if you were feeling disconnected and alienated (regardless of race, ethnicity, religion, sexual orientation, profession, etc) and if you felt insecure, then it could be seen as not speaking to your concerns. If you are told it is already great and you are not doing great at all, that does create a disconnect.

It also was not good messaging as it was projected into the face of a 'change election'. It literally could be perceived as saying the status quo was already great, when for a very very diverse group of people it was not.For example, A-A voting levels cratered from not just 2012, but from even 2004 levels, see an extensive discussion of that here ( https://www.democraticunderground.com/128736610#post18 )

The entire dialectic was moved from what we could do to make peoples' lives better to a 'we are not them' and attempts to shame or outright bait (ie. basket of deplorables) people, which then boiled down into a food fight, further distracting from our substantive messaging. Many people felt like it was no long about them, they were being talked past, not talked to. Buttigieg never ever went after Sec. Clinton on a personal level, it was a critique of the messaging of the campaign. There is nothing divisive at all in his framing of his campaign. That is pure spin from people with agendas of attack themselves. They see Buttigieg surging in the polls (up to 3rd in Iowa, and has shot from 0% to 11%, probably higher now, as that was a week ago or so) and start up the attack train.

This story referenced in the tweet was 2 and half months old (the original tweet itself was 2 months old), and was lying there dormant until a Twitter bot/troll train latched onto it and dumped 1000 plus comments (many bots were removed as we watched it) in a few hours. It literally had almost no comments before the Twitter troll army found it a couple days ago.

Perfect example of of a previous attempt at the exact same thing by a notorious troll (slapped down by Wonkette) can be seen right here https://www.democraticunderground.com/128733687
