For the same reason that the left wants to redefine terminologies like "marriage", "woman" and "racism", they want to redefine "abortion" in order to compel more people to vote for their policies, which 100% NEVER has anything to do with what the unsuspecting new supporters really want.
For example, Asians and Jews are categorized with "whites". This justifies Pro-Hamas groups to exercise anti-semitism because Jews are simply "white" colonizers. Successful Asians are supposedly taking away spots at Harvard from Black and Brown candidates. But if they're categorized with "whites", then they're no longer a marginalized group. That's why the Hmong were holding pitchforks when they were categorized with the Chinese. God forbid they lose Southeast Asian status and the welfare stops coming.
I recently read an article about a Texas soon-to-be mother who contracted an infection whilst pregnant. This could cause lead to sepsis, which could result in death for both mother and the baby. Now surely THE DOCTOR WOULDN'T SUGGEST KILLING THE BABY.
What would happen is an induced labor - meaning she would be given a solution to cause premature contraction and have the baby early. The baby, if it hasn't reached 37-40 weeks, may be put into an incubator and etc. And premature babies always have a higher risk of survival. BUT THE INTENTION IS NOT TO KILL THE BABY like the true definition of an abortion.
But the LEFT wants to re-label this procedure as an abortion. Therefore, if abortions are banned, then doctors can't induce labors.
This has sent all sorts of wannabe moms into panic mode.

Rather than call BS on the Dems, many gullible women are ready to sell their soul to evil Dems.

I'VE DONE THE RESEARCH. There is very little times that a woman needs to have a medically-necessary abortion to save her life. And even if she did, it's actually not an abortion.
The only time that I've personally known someone who had to remove an implantation was my 8th grade English teacher. For some reason, the egg implanted in her fallopian tube. It's called an etopic pregnancy. However, the egg never develops into a baby (so yes, in this case it really is just a clump of cell tissues), and may be a risk to the woman if it doesn't exit on it's own. Therefore, a surgeon will have to remove it.
