Obstruction of Justice is not below the standard for impeachment. Mueller is the one investigating - not Rosenstein or Strzok. Dershowitz has no idea what Mueller has, so he is just rattling off his presumptions of what the investigation has found and his opinion should be looked at in light of that lack of knowledge.
It doesn't matter anyway. Impeachment is not a matter of law but of politics. If Congress votes to impeach and convict the President, he is impeached and convicted regardless of whether he broke any laws.
Also Alan Dershowitz is a supporter of war crimes, murder, and apartheid so for him to pretend to be invested in liberal principles is funny.
