Most of the so-called conservative talking heads stop short when it comes to Obama. They put their careers before the truth, just like the liberals do.
Although I understand the position of some conservatives who say we have a better opportunity for victory by focusing on Obama's record, it bothers me a great deal that otherwise respectable self-promoted "conservative talk show hosts" and "constitutional scholars" not only won't even talk about this, they (specifically, Hugh Hewitt and Michael Medved) characterize anyone who questions Obama's eligibility for the office as "coo-coo", "nut-cases" or "lunatics". I conclude that to some folks, defending the Constitution depends on whether or not it would be disruptive or inconvenient to them. Cowards all.
