Nancy Pelosi has a not so easy decision to make. She can sit on the articles impeachment, which will very likely anger her cohorts. On the other hand, Nancy can transmit them to Senate and face the nightmare that 2/3 of the senators just might vote “not guilty.” Either decision will make her look really bad. However, if there are a significant number of the democrat senators vote not guilty, it will likely end her political career, and maybe a few of her committee chairmen too.
On the other hand, it could destroy any chances that Biden has to run for president. If he and his son have to appear as witnesses, they just might have to take the 5th or end up in prison.
I certainly wouldn’t want to be in her shoes right now. (Besides, my size 13’s wouldn’t fit.)
