Feel free to discuss.
For my part, I can understand a Democrat endorsing a liberal Republican or even a moderate Republican in certain cases (e.g., if the Democrat is corrupt or racist or somethiung). To endorse a right-wing Republican like Bob McDonnell, though, against a good Democrat like Creigh Deeds, is very hard for me to understand. Yet the first words of this individual's Washington Post editorial are, "I am a Democrat."
What. The. Hell?
