Bush was wired?

Rumour goes that Bush was wearing an earphone during the first debate in Miami, so Rove or another adviser could tell him what to say to Kerry.
Here and here some articles.
It could explain his long pauses and some of his repetitions. When his whisperers realised they couldn't keep up over the earphone, and that Bush was getting confused, they may have reduced it to just telling him stuff like "say how hard the work is".
There have also been many previous reports of Bush using a wireless earphone for speeches. In one amusing incident, they actually somehow picked up the wrong feed, and there were several seconds of two-voice broadcast, with someone else saying the speech a few seconds before Bush.
I propose that next time the two candidates go through a metal detector.
