Ms. Stock appears to be an intelligent woman.  Lisa's first comment about Trump was clear to anyone who can comprehend.  Since then, she's said she doesn't endorse Trump, is not a fan of Trump.  That Ms. Stock wrote an op ed saying Lisa Murkowski supports Trump is a lie.  Bad enough, but since Ms. Stock is a retired officer and a former West Point instructor, she has violated the Honor Code and disgraced her self and her service.

As for Lisa needing Mark Begich to draw Democratic support for her bills, were you aware that Lisa is the 4th leading Republican to draw Democratic support for her bills?  And that's AFTER Begich got tossed out of the Senate by a majority of Alaskans.  

As for your prediction that Lisa would be ineffective in a Senate dominated by Democrats, Lisa got more bills passed last Congress when Democrats were in charge than Mark did.
