She looked at Biden who did left things and what did that get him? Lose the house for years 3 and 4. And polls showed he was going to lose. Aka the left never showed up even after getting some left things.
Harris ran on women's rights, mf'ing democracy, and while she didn't say it it was clear there would be continuation of student debt relief, green energy, EVs, infrastructure, etc. But it didn't work because "it's the economy, stupid". The left couldn't even show up for their own human rights.
