Another aspect of this— As Tapper’s thread demonstrates but doesn’t say, Trump’s claim about Obama is a lie. It was Trump’s tariffs that really hosed the lobster industry. But if you try to google what Obama’s impact was, you’ll get like six pages of news items repeating the lie. https://twitter.com/jaketapper/status/1275978725109178368

Those news items by and large don’t contest the lie or give objective information on the industry.

Wading further into the results, you might learn about a remote marine preserve Obama created to protect endangered species, which Trump revoked. https://www.boston.com/news/politics/2020/06/09/new-england-aquarium-trump-administration-national-monument

News orgs, by not clearly identifying this stuff as lies, are practically flooding the internet with Trump propaganda and, if you’re actually trying to determine what’s up with the Maine lobster fishery, it can be hard to find the truth underneath it all. https://www.npr.org/2018/07/14/629058592/tariffs-hit-maines-lobster-industry

I put a box around the Obama years.
