Let there be not a hint of doubt that Vice President Kamala Harris is getting loads of unsolicited advice from experts, faux experts and just plain folks who want her to be elected president this fall.

You may count me as one of those folks.

If there is a lesson to be learned about why Hillary Clinton lost to Donald Trump in 2016, one need look no further than to the grievous strategic and tactical errors Clinton made down the stretch.

National polling had Clinton leading Trump by 2 to 3 percentage points; that polling, by the way, turned out to be accurate, as that was the margin of the popular vote victory Hillary scored against Trump.

But ….

She erred in refusing to visit three key battleground states down the stretch: Wisconsin, Michigan and Pennsylvania — all of which went for Trump on Election Day and sealed his Electoral College victory. Clinton took voters in those states for granted, thinking they were in the bag for her. So, why bother?

Clinton learned the bitterest lesson imaginable. She most certainly should have bothered.

What might be the advice that Vice President Harris receives as the 2024 campaign ramps up? Do not, under any circumstance, take the voters of any state for granted. Harris will have plenty of polling experts in her corner. She’d better heed their advice.

And if that advice tells her to visit certain states that might appear to be too close for comfort, she’d damn well better heed it.
