At the time Bush began his stint in the Air National Guard, he was 22 years old. When Obama was 22, he was still a student at Columbia University. An investigation along the same lines as the Bush Air National Guard investigation would be impossible because Obama has not allowed the release of his college records. Unfortunately, the media seems to be perfectly content with this lack of access to key events in our presidents past and for all intents and purposes considers the matter to be a non-issue.
The birthers are naturally being drawn to and are fueled by the alternative media because nearly all of the negative press Barack Obama has received, including his controversial associations from his past, has originated with these sources. While most of the media treated us to puff pieces during the 2008 election, investigations into Obama associates like Reverend Wright and Bill Ayers percolated and exploded almost exclusively out of traditionally conservative outlets and the blogosphere. Mainstream sources on the other hand fiercely fought to discredit these stories, even when these controversies deserved scrutiny and provided a rare insight into candidate Obama.
President Obama's secrecy about his past and the media's apparent lack of interest in it does not assume that they are colluding to cover something up, but it does leave plenty of room for people who are conspiratorially inclined to fill in the blanks. Seeing as the left increasingly sees the birther movement as an albatross to tie around the neck of their enemies on the right, we can most likely chalk up the media’s lack of curiosity to good old-fashioned left wing bias. But even if bias is to blame, it's only natural that some would confuse their lack of investigation to be evidence of malfeasance.
Presuming the media’s love affair with President Obama continues, we can assume that their lack of curiosity will as well. For those who profess such admiration for the President but don’t seem to care much about whom he was prior to his emergence on the public stage though the question remains: Are you scared of what you'll find?
