Roll Call says yes. I have no idea about the inner workings of Johnson's office. But I can imagine that somebody use to dealing with the efficiencies of running a business would struggle with political staffers...and vice versa. Again, just speculation. And that assumes this report is even accurate. Which I guess we'll find out.
I can also imagine that Ron Johnson doesn't do well at DC schmoozing...which seems to be what's written between the lines here..."the senate is still about building relationships..."
