Presidential Pretention

According to this Military.com article, Obama is "considering deploying National Guard troops to the border."

Huh.

He "doesn't want to 'militarize' the border," BUT...

Well, what would you call it when you have military forces on the border? What's wrong with "militarizing" it?

I'm all for militarizing the border to keep cartel violence out, (though preferably by arming citizens), but it seems to me that the President is missing a step in the chain of command.

He doesn't order Guard troops anywhere.

He asks the governor of a state if he (or she) would be willing to allow the feds to temporarily mobilize some of that state's Guard forces.

As a Guard family, (and there's a big reason I like being state-level), I find this mingling of federal and state powers rather troubling - especially given the Arizona's governor's angling to make sure her state's Guard is mobilized under federal authority.

Am I just way off-base here? Does this happen all the time? Or am I right to be bothered by it?
