It's easy to figure out why WI GOP Sen. Ron Johnson did not join

the show of independence and respect for the Constitution displayed by a dozen of his GOP Senate colleagues who voted Thursday against Trump's invocation of a national emergency to seize border wall funding which Congress had appropriated for other purposes.
For one thing, Johnson owes Trump for signing into law last year's tax cut bill which included a sweetheart corporate provision demanded by Johnson.
You scratch my back, I'll pretend I see your national emergency.
And Johnson could not criticize Trump for grabbing executive power, since that's a sin which both he and Johnson have said was the way Obama did business:

For the past eight years, Republicans skewered President Obama as an "emperor" who acted outside of his "legal authority" for the executive orders he issued from the Oval Office. Now, they are cheering President Donald Trump as he issues a raft of his own...
Wisconsin Sen. Ron Johnson said Obama had “exceeded his executive authority” and was acting “without legal authority" in 2014, following Obama’s immigration executive orders.No way Johnson remotely suggests Trump has anything in common with the previous President whom Trump is trying to pretend was never President.

"Obama unilaterally changed the law," Johnson said. "That's not our constitutional system."
