Most of the polls are also very old... 2 to 3 weeks old... even back to when kamala received her poll bump when she was first anointed as the Presidential candidate.
The liberal pollsters have done polls but they are not releasing them (likely because they are so horrible for kamala!
NOTE: The liberal pollsters were (maybe still are) planning to falsely jack up polls to show that kamala was leading after the DNC convention but Trump highjacked their planned news cycle with his dump that Kennedy was joining him (or at least pulling out from the crucial state elections that will decide the elections)!
