Especially when he's been given such a broad platform with the mainstream media. And the overwhelming acceptance to the debates so he may put his ideas out against Romney and Obama.
I don't know the answer to this, but I suspect that if he truly had the following of enough people he'd be given equal air time. If he only has 2779 financial contributors, the network are not going to give him a voice. They are in the business to make money as well, and an audience of 2779 is not going to help in their efforts either.
It a vicious cycle, you have to have a following to get equal air time, but you also have to have equal air time to get a following.
