Kennedy was almost 60 years old when he became a republican. Not had time to research it, but if he’s still pro-abortion that’s not good. The majority of his elected life he was a democrat, becoming a republican in 2007. I would suspect he claims pro-life now, which is good. Still light-years better than any democrat, unless he turns into Lindsey Graham.
I became a Republican forty years ago and haven't once looked back. Democrats of fifty years ago were "blue collar" Democrats and believed differently about things. Now THEY are gone with the wind.
ANYone who claims to be a Catholic MUST have voted against the "abortion-on-demand" party. Otherwise that person should turn in his/her rosary and become (in alphabetical order) animist, Buddhist, Jewish [https://en.wikipedia.org/wiki/Judaism_and_abortion] or Protestant.
EVEN the Saudi Muslims don't practice abortion. It is anathema to them. They accept and love all their children.
I hope Kennedy has changed his views on abortion.
