Oh, because he dosen't support your POS in office?
Sasse announced that he would not support Republican front-runner Donald Trump should Trump become the party's candidate;
he was the first sitting senator to make such an announcement.[37]
Sasse questioned Trump's commitment to the U.S. Constitution, in particular accusing him of attacking the First Amendment; he stated that Trump had refused to condemn the Ku Klux Klan; and he suggested that Trump "thinks he's running for King".
Isn't it all about the Constitution?
Ben Sasse
Oh, and it doesn't mean Trump is doing it all wrong either, he has quite the battle going on.
