She’ll be better in debates for sure, but she’s not well liked as far as I can see. She didn’t even make it to the 2020 primaries because she was polling so low and her polling has plummeted along with Biden over the last 4 years. She needs to win over “moderates” and a good portion are still sexist and racist. She’s got an uphill battle and an open competition to find the best candidate instead of the next on the succession list seems like a much better idea.
