On two important policies — sanctions on Russia and health care — a working majority of Democrats and Republicans in the Senate has already thwarted Trump. 

Another bipartisan majority appears to have formed against Trump’s threat to shut down the government unless he gets significant funding for a wall along the Southern border.


 In fact, on any number of issues, there are enough anti-Trump Republicans in the Senate not only to block the president but also to push their own policies contrary to the president’s — as was the case with Russia sanctions.
