I don't think that Obama twisted anyone's arms. He had Dems entirely on his side with both the House and the Senate for the first two years. Then he had a phone and a pen for executive orders for the next six. During that six the media was entirely on his side and the judiciary did not seem to challenge him. Johnson, on the other hand, was a master arm-twister.
Trump also has had to do everything he does under the cloud and threats of the phony Russia investigation.
True
Phony investigation from the GOPe, which makes it worse for President Trump.
