You and many others got banned, but quite a few others left voluntarily (myself included) during the 2012 primaries and general election.
If you didn’t support the candidate du jour, it was a tough slog.
Many of those who left have never come back and I miss their insights. You can sometimes meet up with them on other conservative sites.
Correction. If you supported the abortionist/homosexualist, big government healthcare pusing liberal, it was a tough slog.
