I just overhead a reporter on CNN citing poll results indicating that 2/3 of Americans polled could not name a single Democratic presidential candidate. I’m not sure I believe that figure, but that’s what they said. If true, it’s moderately bad news I suppose.
However, a larger portion of the half of Americans who vote presumably can name a candidate. For example, if all respondents among the 1/3 who could name a Democratic candidate were also among the half that vote, then the stat would change to “2/3 of likely voters can name a Democratic presidential candidate.”
