I use Bing all the time, often for candidates names. I have never gotten that. Just tried searching Trump, Rubio, and Cruz and got no such graphic. Maybe it’s based on your past viewing.
It varies. If you type Jeb, you don’t get the graph, but Jeb Bush gets you there.
Likewise, type Trump and you don’t get the chart, but type Donald Trump and you do.
But with Hillary or Hillary Clinton you get the chart. Go figure...
You’re right. “Progressive” is definitely a loaded word. And who isn’t for “progress”. That word is a very clever masking of truth.
