Precisely! We get them in my overwhelmingly Republican county all the time - - rats who want to get elected know that they must be "Republican" to ever make it happen. So they switch registration but remain putrid rats at heart.
Unfortunately, that strategy is pretty much a one-way street since few Republicans ever want to live in, or get elected in, a rat's nest. Rat's tend to vacate their own nests after fouling them and move on to new climes to foul.
Mine, too. I am a Republican officer in my county, and I have outed several turncoats, and done my best to derail their political careers.
We only have only democrat elected to countywide office. We also only have one Republican official that I think still has democrat tendencies.
