This is ridiculous to say it's better if he's excluded.
The masses aren't exactly tuned in as a lot of Ron Paul supporters are, and if you tell them their only choices are the 4 or 5 people on the debate, they'll believe it.
To quote my father, who is old and out of touch "You can sing and praise Ron Paul, but he's nowhere on TV". Yes, that's a dull view, but it's the view the voting masses hold. We live in a generation where everything in the mass media is the gospel, and everything else is not credible.
