I don't think Kellyanne Conway is worried that people will think she agrees with her husband.
Perhaps she's just a stronger personality.
Then there is “Snakehead” James Carville and his wife Mary ??? who make decent money working for opposite sides of the political spectrum . . .
However, it is disturbing that Kellyanne Conway's husband makes public any views that conflict with his wife's. Given the nature of her role, he should keep his mouth shut (so to speak). It's inappropriate and disloyal of him to be doing anything that could embarrass his wife. I find his behavior troubling and probably a sign that there's trouble brewing in their marriage.
