I choose what I'm concerned about.
The effects of Trump's weight gain are and could potentially be dramatic in my mind.
First, in and of itself, the weight gain is dramatic.  There no question about that.
But, Putin is weighing (no pun intended, just channeling Sarah) in on Trump's vitality and physique.  What effect will that have?
Trump has to literally and figuratively take this issue off the table.  Not by putting things in other people's mouths (telephone conversations), not by directing things into people's mouths (his spokespersons), and DEFINITELY NOT by putting more things in his mouth. 
This is an issue, and will become a bigger one.  Literally if Trump is not careful, but, in terms of the danger to America, figuratively as the international community follows Putin's recent lead.
My concerns are based on objective observations.  I'm doing birthering, claiming Obama is a Muslim, Claiming Obama is a Muslim or against the 2nd amendment, claiming Death panels.
