———they do not fear Obama like the rest of us do.-——
No, that is not the reason. If you read the posts, fear of Obama is acknowledged. The reason for not becoming part of the Republican coalition is the notion of principle, of maintaining conservative purity.
The concept of sticking to one’s conservative principles in a presidential race where conservatism is no longer an issue is given a higher value than defeating the liberal scourge. As has already been made plain, that is acknowledged in writing, upthread, declaring one’s self irrelevant in the Presidential election is preferable to sacrificing conservative principle.
Conservatives were defeated in their attempts to determine a nominee for President. Some have determined that the proper course is to opt out rather than to vote for a person who lacks the required purity.
