ONe thing causing the stark contrast is that they clearly used some kind of lens filter on her at the debate. Also, there was some kind of lighting on her podium.
They used TV/film makeup on her for the debates. For the recent speech, she looks like she’s wearing street makeup put on under natural light. That stuff disappears to the camera and fades under stage lighting.
I really don’t care. She’s a messed up person whose humanity is shriveled to nothingness. However, I don’t think for a minute she believes looking old and haggard will help her in the future. She’s vulnerable and nearly alone and she knows it. She can and likely will work behind the scenes, here and there from now on, but her time for ascendant leadership is gone and she knows it.
