Robertson’s endorsed him for the same reason I would have voted for him, if I lived in the 5th.
Jindal is a doppelgänger.
He was an unknown as far as politics is concerned before he ran. I claim no clairvoyance when I said last fall that the man was poseur and likely RINO. I merely contacted folks who I’ve worked with and trusted for many years in Louisiana politics. They’d never heard of him.
I didn’t need to know anything else.
