It's almost like she's a believer in policy rather than partisanship. Do the right thing, receive the appropriate praise.
Which is of course evidenced by her demonstrated record in continuing the charge that Trump is a racist despite his administration enacting the most comprehensive criminal justice reform in forty years, working alongside Van Jones of all people to get it done.
No one wants partisan bickering right now. I give her credit for understanding the poor optics of engaging in that type of behavior when people are worried about their health, homes, jobs, 401k's, etc. It's more than I can say for certain members of the media that think it appropriate to tweet at the first lady to #beinfected, or conversely try to use this as their soapbox about border security.
