Huh ?
Kennedy and Biden have sewed up the "suburban single woman" vote, since they want absolutely no restrictions on abortion.
Trump's only play to get their vote is to sell his soul to Moloch and choose Gabbard as his VP.
If RFKjr had come out as pro-life or even mostly anti-abortion, he could have taken some votes from people who don't want to vote for Trump but REALLY don't want to vote for Biden. Now all the pro-aborters are going to split between Biden and Jr, and the pro-lifers will go to Trump by default.
P.S. This assumes, of course, that there are no black swan events, like Biden dropping dead or out of the race, and/or Jr doing either of those.
