What can we do to get them back?
How about this: Obama met Trump today in the White House. The meeting was scheduled to take 10 minutes but lasted over 90 minutes. Trump left saying that Obama was very nice, and Obama said he would do anything he could to help Trump.
Trump himself and his immediate sycophants have no idea how politics works. I would not be surprised if Obama ends up being one of Trump's closest advisers. Obama DOES understand politics very well and he has dealt with an uncooperative Congress his entire administration. Trump ran against the Republican establishment, so he will probably find himself in a similar situation. Obama will probably be the only person who can guide him.
As far as Trump's kids being "his closest political advisers", that is beyond laughable. His kids have never held ANY political office. They would give him no better advice than anybody off the street.
