She is correct. Pro abortion voters are numerous and completely one issue centered. The pro lifers were already 100% Republican. Now, the airheaded 18-35 year old women who didn’t vote are flocking to the polls. You can guess who they will not vote for.
If the Republicans announce that we're pro-choice, we take away that issue from the Democrats.
Previously, that voting bloc didn't show up to vote in great numbers. But now their turn out is very high and it will remain that way as long as abortion is an issue.
