You won't be informed of this by reading the article, so let me ask you if you realize who benefited from this particular fraud? The article actually says that this is "all about electing Republicans," but the Republican establishment isn't the one pulling out all the stops to elect a particular candidate.
"[I]ndependent voters who switched their registration to the Democratic Party were allegedly told they hadn’t registered at all, forcing them to sit out the closed primary."
How would disenfranchising Democratic primary voters have anything to do with electing Republicans?
There are none so blind as those who will not see.
