McCain is Too Ignorant to be President?

Many on the left are trying to make the argument that John McCain is too ignorant about foreign policy to be President because he conflates "Shiite" and "Sunni."

While this is not unimportant, I humbly submit that neither Clinton nor Obama seem to be aware of the fact that most of their proposals for domestic policy -- most particularly, universal health care -- clearly violate the Tenth Amendment, and that understanding the Constitution and respecting the rights of the people of the United States is a lot more important to being President than understanding the differences between various Muslim sects.
