Past polls show how the favorability of previous vice presidents changed during their first four years in office. Harris' net favorability is slightly lower than that of former Vice President Mike Pence at this point in their respective tenures, and it's well under the ratings of three previous vice presidents.
Whatever the reason is, it is what it is. But, for the sake of argument, wouldn't the libs be able to see through the disinformation and give her a positive rating? Face it, she is not liked even in her own party and totally unelectable for POTUS. She's already shown herself to be a quitter by dropping out before the first primary in 2020. Or, do you need a link for that too?
