I find it strange that they are blaming the progressives for Trump..
The Israeli papers are also "stunned by Trump's incoherent rants."
Why aren't conservatives stunned?
Because the public record shows that most conservatives admire and support abject ignorance.
Don't take my word for it:
Bedtime for Bonzo, Dan Quayle, George Dumbya Bush, Sarah Palin, Donald J. Trump
