No, they are supported by those who know that there is not a dime's worth of difference between the Rats and the GOP.
I am amazed that there are any Freepers who continue to think that voting for the GOP makes a difference in spite of the overwhelming evidence that clearly shows it does not. Some of the most egregious big government legislation over the last 60 years have been enacted by GOP presidents.
Then, just when these people think that the GOP has managed to create a conservative Supreme Court, a bozo like Roberts shows that that isn't even true.
It doesn't make sense not to vote 3rd party.
