This is a function of the various ad campaigns. Vance has begun more TV ads, which has raised his name recognition. Gibbons and Mandel got into an unattractive spat during a debate, instigated by the dishonest Mandel but tarring both, leaving Gibbons appearing shallow. Timken has begun her tv ads, and may appeal more to independents but that won’t help her in the primary.
JDV is my pick. dont believe the anti-trump smears, he could be as potent as Rand Paul. Its no contest.
What Trump’s initial run showed us was that 95% of all these guys are just place-seekers at the troughs.
