This is a primary.
DeVore and his supporters aren't saying why he's better, they're saying why his fellow candidates are bad.
They're creating a theme for Boxer to continue and exploit after the primaries. And you can bet your last dollar that will be the modus operandi of the Democrats.
What was Reagan's 11th commandment?
"Thou shalt not speak ill of any fellow Republican."
Don't tell me why Fiorina is bad, tell me why DeVore is good. The former eats away at the conservative movement in general, the latter builds it up.
