You call it sore loser, maybe it is.  But that's politics.  To be successful at politics, Trump needs to build relationships with everyone he'll need in the future for a vote.  Especially if he gets impeached.  Ronald Reagan knew this, which was why he was so successful getting bills passed with a democratic majority in Congress.  Reagan NEVER insulted anyone, he had a great sense of humor, and he knew how to communicate with a broad range of the American people.  After the last vote, Trump vilified McCain,  Murkowsky, and Collins.  While you MAGAphants think he's talking tough, he's really talking stupid.  We who oppose Trump are thrilled every time he attacks republicans.  It's just making it harder to implement his ridiculous ideas.  Not a typical politician, and that's good for the Democrats.
