Do you have anything to support that? I haven't found anything yet.
She used to be a Republican but there were reports that she jumped the shark on the Iraq war after 2004 - said she supported Hillary originally but also mentioned the Republican presidential primary debates on the view in 2008 and how she wanted them to debate an actual plan for immigration. [eventually she said she was an independent - didn’t consider herself tied to either party]
I have no idea how she ultimately voted but it’s sad that she used to be a solid Republican and possibly got bamboozled. I’m not sure if she was a PUMA or went for Obama - unfortunately most Hollywood types got rabid when Palin became the candidate - as well as a lot of my younger friends.
