Using standard partisan campaign logic for this cycle, if no one admits to it would that mean that it must have happened even more than some people suspect?
Oh, I'm sure it has happened. Although that usually just gets used as the partisan basis for moving to a closed primary system. It's what happened in my home state back in 2010-ish IIRC. 2008 was the last primary election I voted in because I refuse to register as a member of a political party. Although I'll admit I'm a Republican leaning independent, and pretty much always have been, which is why I participated in their Primaries(well, that and in many practical ways, the Republican Primary often is the deciding election for many/most seats, as the Republicans dominate the General Election in my area usually).
But they said I'm no longer welcome at that vote, so I stay out of it. If they choose poorly, well, they find out why I say I'm an independent.
