I think that's because language about Congressional Consent is missing from the Natioanal Popular Vote bill.
According to their bill, Article IV says:
"This agreement shall take effect when states cumulatively possessing a majority of the electoral votes have enacted this agreement in substantially the same form and the enactments by such states have taken effect in each state...The chief executive of each member state shall promptly notify the chief executive of all other states of when this agreement has been enacted and has taken effect in that official’s state..."
There is no provision for Congressional consent. Until enough states pass the compact such as to bring it into force, the issue is moot. Congress should not vote to consent to a compact that has no force and is just a desire.
It seems to me that the interstate compact has to first meet its own requirements to be in force, and then second, attain Congressional consent before it can be enforced on the nation.

I would think the very persuasive arguments against the 17th amendment and how it has resulted in LESS representative government would be enough for these clowns to see they are pushing something that will harm them. But I think they are really just tools of a more nefarious Cloward–Piven cabal. The notion they are gaining some sort of identity by hitching their carts to the philosophy that has caused so much death and misery is beyond me. But it is the popular culture these days (at least for now) so I guess they are the product of it. Not something to be proud of in my opinion.
