A number of friends of mine have commented on an odd phenomenon that they have observed-- conservative Republicans they know who are saying that they are going to vote for Barack Obama. It seemed at first to be an isolated fluke, perhaps signifying only that my friends know some strange conservatives. But apparently columnist Robert Novak has encountered the same phenomenon and has coined the term "Obamacons" to describe the conservatives for Senator Obama.

Now the San Francisco Chronicle has run a feature article, titled "Some Influential Conservatives Spurn GOP and Endorse Obama." In it they quote various conservatives on why they are ready to take a chance on Barack Obama, rather than on John McCain.

What is going on?

Partly what is going on is that, in recent years, the Congressional Republicans in general-- and Senator John McCain in particular-- have so alienated so many conservatives that some of these conservatives are like a drowning man grasping at a straw.

The straw in this case is Obama's recent "refining" of his position on a number of issues, as he edges toward the center, in order to try to pick up more votes in November's general election.

Understandable as the reactions of some conservatives may be, a straw is a very unreliable flotation device.

If all that was involved was Democrats versus Republicans, the Republicans would deserve the condemnation they are getting, after their years of wild spending and their multiple betrayals of the principles and the people who got them elected. Amnesty for illegal aliens was perhaps the worst betrayal.

But, while the media may treat the elections as being about Democrats and Republicans-- the "horse race" approach-- elections were not set up by the Constitution of the United States in order to enable party politicians to get jobs.

Nor were elections set up in order to enable voters to vent their emotions or indulge their fantasies.

Voting is a right but it is also a duty-- a duty not just to show up on election day, but a duty to give serious thought to the alternatives on the table and what those alternatives mean for the future of the nation. Continued...
