Do 90% of Americans support background checks for all gun sales?

In the first hours after the Las Vegas mass shooting, many leading elected officials in Wisconsin issued statements about prayer and condolences, but Milwaukee County Executive Chris Abele went further.

Abele, a Democrat who holds a nonpartisan office, said in a tweet on Oct. 2, 2017:

Americans have overwhelmingly supported common sense gun reform. 90% support universal background checks. Elected officials must act.

… So, what about Abele’s claim about all Americans? CONT.
