that is birther levels of stupid. muscle is more dense than fat, and thus weighs more.
Also, when was that picture of trump taken, 10 pounds ago, maybe Trump's lost a few pounds since he got elected?
This is the perfect illustration to what the liberal bubble must now do in order to maintain the desired levels of Trump derangement syndrome. Everything is spun into the liberal narrative of "Trump's a disaster", even his doctor's exam.
This particular example is just blatantly obvious using the logic you pointed out, but it is among the overall trend since he announced his candidacy.
Other such examples of liberal spin includes all iterations of:
Trump is loosing his mind
Trump is a racist
Trump hates minorities
Trump colluded with Russia
Trump will start WW3
Trump will destroy the economy
None of it is true, but it's all projected loud enough to hook people into thinking it's true.
What's going to happen? Well Trump has been working his *** off and knocking down these things one by one:
He is in excellent health
Black unemployment down to it's lowest level ever.
Minority employment up
No russian collusion whatsoever
North Korea de-escalating because of Trumps policy
Record manufacturing jobs, and a booming stock market
This work and the reality it creates is shrinking the bubble, and quickly too. In response to this, the bubble has to get louder and more salacious in order to keep people inside (which is what we see with the SI article). Ultimately it WILL pop, or at least get so small that it won't really matter. This will be a good thing in the long run, but when it does the people inside are in for one hell of a hangover.
