Well let me see, first your would need to define Rino. Then I would be curious how many Republicans would be purged by your definition.
What I would suspect you may find out is that if you get rid of everyone that is defined as a Rino by many here you wouldn't have enough voters left to elect very many people.
The plan laid out in the article starting this topic has merit if you start out with an understanding that it takes many more people than just strict conservatives to win an election and understand other peoples views you might have a chance to turn the Republican party more conservative.
However you might find that purging everyone you think is a Rino would leave you with a minority that couldn't elect anyone.
RINOs are easy to define: Any member of the GOP who thinks big government is a good thing.
They can’t win without us.
If that is the case then the US is doomed. A strong Conservative movement is the only hope for America. Socialism or Socialism-Lite gets us to the same place only at different speeds.
Conservatives don't have the numbers to field and elect our own third party candidates.
We do have the numbers to often make the difference; to deny success to undesireable candidates and to push desireable candidates to a win.
McCain's tactic is to win without conservative support.
He wants to move left to pick up liberal swing voters to make up the difference and break the bond between republicans and conservatives.
If conservatives support him as the least evil candidate and he wins we will have helped him destroy the conservative movement.

Too late, the GOP is already there. I'd rather have a strong minority of conservatives that build on those principles than a bunch of "winners" that agree with the left but think pairing it back by 25% is a victory.
Instead of defeating our rivals they want to give up and agree with their premise. Example: here in Tennessee the governor and the Dems (along with RINO's) wanted to raise the cigarette tax by 40 cents a pack. My so-called conservative state representative in the most conservative county in TN (and practically in the US outside of Utah) wrote to me saying he wanted my help to "cut the governors request to only 20 cents a pack".
He didn't fight to say "Hell no", he admitted defeat an wanted me to "fight" to just get screwed less.
I don't play that game.
