Why is it that I've literally heard more news about Marco Rubio drinking water than I have that Obama can?

Because you are not watching or reading the best news sources. On NPR, the drone problem is discussed often, and the only mention (on NPR) of the water has been on an NPR comedy show.

Also, the drone problem is a very, very tough one. If we put Americans on the ground to fight these people, we end up with dead Americans, and probably more dead foreign nationals. But, if we do nothing, the organizations that want to destroy the US will grow in strength.

How do we decide: do we do what might seem fairer (send in your brother and sister to kill and be killed) or do more limited harm via drones?

But the water issue is a simple-minded one: Rubio repeated Romney's ideas, and did something that looked creepy. It's funny, it's easy to think about it.

Also, Obama had more voters than Romney, so we can assume that there are more Obama supporters than Romney (aka Rubio) supporters.

The administration is trying to draw attention away from themselves and Libya.

You're watching/listening to the wrong stations.

You watch the wrong channels, and too much tv.
