Convictions

Someone who comments on Bob Parks' 'Black & Right' blog as 'The Machine' posted a comment I wish to share with Gentle Reader:

"A man is only as wrong as his convictions will allow."

For context, the comment was made in response to Nicolas' question of why certain Republicans, such as John McCain or Scott Brown, won't hold the line against "liberalism." Or, to put it another way, why are there RINOs?
