First of all, most of it was done prior to the debate. Second, it is just ONE poll as Lester is the master of cherry picking polls. Third, she is leading the race but trailing with independents? Dubious. Fourth, the poll didn't even take into consideration if the people polled are even registered to vote!  Did Lester (or you) bother to tell us any of that? Of course not.

What Lester is "consistent" with, is cherry picking polls, using obviously discredited/partisan polls, touting a company (538) that helps his side but then throwing shade on the same company (again, 538) when it backs Harris and he is also consistent with leaving out links. That is just all deceitful at best.
