You haven't been paying attention. Obama spent eight years infiltrating unelected loyalists at every level of power throughout Washington DC. Something like 95% of all government workers are partisan Democrats, from the supervisor with the nice office to the person cleaning the toilets. and everyone in between. And they're all doing what they can to hobble Trump.
Why do you think he bought a house in DC? He and Valerie Jarrett are running the show.
What party would you belong to if your livelihood depended on bigger gubmint?Government workers, especially in DC, have been mostly democrats since FDR, long before Obama. Clinton did the same thing with placing appointees all over government and Bush/Rove let them stay in place as part of their “new tone”. This is nothing new for democrat presidents to do. Obama did not set up a HQ in DC to make that happen.
He couldn’t run the show while in office (Reid/Pelosi did, and they even drafted the ObamaCare legislation). While Obama put many people in their positions, he can do nothing for them anymore; he no longer has his “pen & phone”, veto power, etc.
He is former president and former “community activist”, nothing more.
