[Betty Jane]

Her not remembering can be considered as a sign of senility. She's looking old and now we know she is having memory problems. She is not healthy enough to be president.

Or she has to admit that she lied when she said she can't recall.

I'll go with old and senile.

[Enchante]

I’ll go with old senile pathological liar.

[nopardons]

She's kinda young to be senile, but there has been some brain damage AND she lies; she has been a compulsive liar ALL of her life!

She is NOT fit for any job at all...let alone the presidency!

There is still a self-protective part of her brain, that is working ( and/or others are protecting her and lying for her and keeping her in wraps! ), so I doubt that she'll ever slip and admit truth; sadly.
