Every election cycle is different.
And every election cycle is the same. You can't count on history repeating itself, but not learning the lessons of history dooms you to repeating mistakes.
Democrats failed to put competent leadership in place when they had the chance. They chose old Joe Biden instead. Who selected a weak vice-president, then appointed a weak cabinet.
Everything about this government exudes weakness and ineptitude. All three branches.
Every leaf and twig.
I don't need history or polls to tell me that unless something mighty good happens, Democrats are toast.
