This method has been suggested many times and many people consider it quick, humane and fool-proof.
Of course the Left hates it. They want horrible, botched executions so that everyone is disgusted and gives up on the idea of capital punishment.
I think you nailed it with your post.

Bingo. Nitrogen is easy, painless and drama free. Why be crueler than needed?
And they know it’s impossible to prevent states from obtaining nitrogen gas.
The Lefties should love it. This is the preferred method of State murder of “incompatible people” in North Korea.
The main reason for going to N2 is that supplies of the gas can’t be effectively boycotted by manufactures like the injections can. That it kills painlessly protects against legal challenges.
Why would any body be disgusted by a botched execution, the more horribly the MURDERERS DIE the more we should all enjoy it.
