I’m dubious on this #walkaway, too, and waiting for November to see. They may be walking away, but I don’t know if they’re walking in our direction.
I officially walked away from the Democrat party sometime in the mid nineties, but I had been a more or less disillusioned voter since the Carter years. I wasn't a reliable voter at all, and stayed home during more than one presidential election.
During the Reagan years, I gave the man sincere props for turning the economy around, and for bringing back a sense of pride to Americans of all stripes. When he succeeded in ending the Cold War, I applauded him.
Still, I wasn't ready to vote for any Republican. It wasn't until I was accidentally exposed to evil right wing talk radio in 1998, that I finally woke completely from my left liberal programming. I registered Republican to vote for GWB in 2000, and never looked back.
I don't think most walkaways today, will wander the wilderness as long as I did, but I don't expect to see them voting Republican this year, either. Maybe by 2020. We'll see.
