So you are changing your story then? You agree it is obviously wrong for Trump to blatantly politicize this issue for his own personal agenda just as it was wrong for Obama to politicize the many different mass shooting tragedies for his own personal agenda.
Yes. With one caveat.
Obama was essentially arguing repeatedly to have Congress to pass laws to systematically remove rights granted to citizens under the 2nd Amendment. And he often made the argument that existing laws, in enforced, weren't good enough, something that was false.
Trump yesterday was basically arguing that a Federal Court Cicrcuit is needlessly blocking constitutional rights granted to the Executive.
Obama would politicize to try and shame the NRA or shame gun owners. Trump politicized really just to insist that the Executive has certain powers granted when it comes to National Security, a view supported by many legal experts who have looked at this issue.
Hence why this should go to the Supreme Court asap
