They were, and they are, dependent on each other. After the inauguration, that is if she win, I believe their "friendship" will disintegrate. I don't like her much, have to admit that, but I have reason to think that DT will be too weak. Some foreign countries don't understand anything else than the will to be using military power when challenged. BHO has failed on that issue. With DT doubt will linger on.
Funny that the same things that were said about Reagan are being said about Trump....along with the same flawed polls. The advantage this time is Hillarys army of illegal, dead and frequent voters.
