Lisa Murkowki is a Republican Senator from Alaska who voted against even opening debate on repeal and replace of Obamacare.
Murkowski has betrayed her constituents. She betrayed them this week by trying to block debate on repeal and replace. Or, she betrayed her constituents when she lied to them in 2015 with her vote in favor of repeal in the full knowledge that her vote didn’t matter because then-President Barack Obama (D) would veto the matter.
