It would be awesome, but also an absolute nightmare.

Let me preface this by saying I have been to see President Obama three times (once at the Rose Garden, once at my school, and once at another school).

If he were to come speak, people who would be able to be on the floor during his speech would have to get background checks so that list would have to be determined in advance. This isn't too complicated, but you'd have to collect full names, SSNs, residency statuses, state of residency, etc. from everyone who will be nearest to the President. These are the people the President comes around and shakes hands with and such.

The speech would have to be first thing in the morning or they'd have to clear everyone out, sweep the area, and then have everyone come back in. The biggest problem would be getting thousands of people through security, many of whom may not have government-issued IDs and I'm not sure what their policy is regarding student IDs. Even when I had a ticket to stand on the floor, I had to wait nearly an hour in line and that was a relatively small event.

Additionally, the President never arrives when he says he will. If someone says he's speaking at, say, 9 am, it's more likely to not start until 10 or later. I've been at events where people have fainted (President Obama actually stopped his speech once to let people know that someone had fainted) because of how hot it gets with everyone packed in and because you are not allowed to bring in anything to eat or drink; it all gets confiscated.
