Some folks might be surprised that the Kennedy family doesn’t consider Vicki to be part of the ‘legend’. There’s a fair chance that while Vicki might be appointed to the spot...it’s only a four-month period then before an election would occur, and some would speculate that at least one other Kennedy (a pure Kennedy) would put their name onto the ballot, just out of dislike for the widow.
Vicki would have to spend money to defend her spot against the family, and then against some Republican candidate. She may realize that’s a tough episode to enter into. On the positive side....she’s buddy-buddy with the entire state Democratic Party leadership.
