I'm having a difficult time thinking that someone at the end of their life, would be so petty, so per-occupied with their dislike for Donald Trump that they would gasp their last breath just to spite him... as opposed to thinking of the greater portion of their lives in context of themselves, their friends and family.
That's her last words? That's what they're going with? That sounds really petty, and I'm not saying petty on RBGs' part, but those who would exploit her death as yet another opportunity to rally their opposition to Trump.
Not to mention that it doesn't matter what her last wish is... that's not how this works and why should it matter what she wants? She doesn't get to pick her successor. No one has ever had that privilege, why her? why now?
Ultimately she was sour, because she had this planned out. She pictured herself riding off into the sunset under a Hillary Clinton Presidency. How fitting for such an icon of the modern feminist to have the first female President nominate her successor? And Donald Trump came in and blew it all up! Ruined her happy ending. That's why she didn't retire in 2009 when diagnosed with cancer. That's why she stuck it out until 2016 and why she clung to her seat and refused to abdicate... she was hoping to ride it out until 2021, hoping Democrats took back the White House.
So maybe she did say those words... maybe that actually was her dying wish... probably not the only thing she said in her last hours, but the one thing the Democrats could use to resist Trump.
