Anyone else struck by the number of presidential candidates running on a first-name basis? Pete, Amy, Bernie, Tulsi, Tom, Beto, and for a while Kamala. In contrast to those who run on their more formal surnames. You know, the folksy thing. Or at least something easier to remember. It works if your moniker isn’t too generic, say like John or Mike or Mary, I guess.
It’s not entirely new. I mean, historically there was Honest Abe and Teddy the Rough Rider and later Ike and Adalai and then Hillary. Or even the initials, JFK and LBJ.
In local elections, our neighbor recently won the mayor’s seat. Well done, Bob.

I wonder whether the first-name thing also comes across as a contrast to President Trump, (whose informal styles tend to play on his surname), and an attempt to suggest a different ethos?
