"The Ronald and The Donald"
This pretty much speaks for itself.  When asked if he would campaign with Donald Trump, Sen. Ron Johnson bluntly responded

“Stump with Trump? Just because it rhymes, it’d be the Ronald and the Donald.”
 
There you have it. Even as other Republican senators try to distance themselves from the most toxic frontrunner in their party’s recent history, Wisconsin’s own Sen. Johnson looks forward to barnstorming across the state right alongside The Donald.
 
But Johnson is just stating clearly what Wisconsinites already know: that he’s not at all interested in listening to the people who hired him.  He’d rather take orders from the likes of Donald Trump and the extreme fringe.
