The article makes a good point, but I don't attribute it to any conspiratorial effort to limit choices. It is all about money and getting your message out. McCain, Giuliani, and Romney have the money and name recognition. They are sucking the air[and money] out of the other candidates.

The second tier candidates will have an opportunity to present their cases at the Presidential debates. Unitl then, it will be an uphill struggle for them to raise money and increase their visibility. Money is the Mother's milk of politics and there are only so many teats available.

"The second tier candidates will have an opportunity to present their cases at the Presidential debates."

Assuming they are allowed to participate.
