I agree.
In Congressional election seasons these polls are not worth much. I imagine in places like CA and MA the Dems are beating the “abortion” drum and have widened a lead that was already wide.
However, in purple states the races are probably tight or leaning right.
Statistics are fun. People basing any life decision on them without understanding how they work are foolish.
I assume that almost all or all of the people who abortion is the most important issue for always vote for democrats. So the important factor would be their turnout. I wonder what the turnout rate for people who are most adamant about abortion is?
