What happened with you and your wife is pretty much what happened between my husband and I. In a conversation after supper one night I mentioned to him that I really liked what Trump was saying. Neither of us was sure he was making a serious run but he listened. It took a few more weeks for me to swing my support from Cruz to Trump but my husband respectfully heard what I said. (He works full time, I retired early so I had more time to study the candidates) He began his own reading of Trump’s views after we started the discussion and was shortly on the Trump train as well.
We are different from most folks it seems in that we don’t have any close family or friends who are libs. Before the election my family got together and while all were planning to vote for Trump several, including my dad, said they really didn’t want to vote Trump, just had to vote against the Beast. My husband was a true campaign champion in changing some tunes with an “angry white working man” point of view. He was fed up with the platitudes and even though he had to go into an angry outburst he made 2 converts. It didn’t actually gain any votes but it gained support.
The same is true for us, well almost. My sister is, or at least was, a Democrat supporter. However, after Reagan I pretty much ceased all communication with her so I do not know if she has changed. I do know that her church was supporting a Hispanic family who ended up robbing them blind and I sort of gathered that this was kind of a slap of reality for her. Especially since I had predicted that probable outcome, which she of course dismissed without thought.
My father-in-law was also a lifelong Democrat voter, who finally realized that the Democrat Party was no longer the party that he had supported all of his life. Because he is 90+ years old, and a veteran of both WWII & Korea, he only has the MSM to rely on for his news. No internet in other words. With my wife's, and his girlfriend's help we convinced him what a crook Hillary really was/is and why he could not vote for her. I know he voted for Trump.
