Not sure. It’s hard to say what her plan is, but it’s possible she’s banking on either Trump’s legal problems sinking him or even the cholesterol taking him.
I’ve read some articles that say she’s staying in the race on principle. I have also read others that say she is staying in to stay relevant for 2028 and beyond. I have also read that she doesn’t have too much incentive to drop out until after Super Tuesday because she has good fundraising; there are still wealthy and well-connected republicans who don’t want Trump again.
Whatever her plan is, she seems to have burned the VP option with Trump.
