Did you read the article? It says it doesn’t necessarily work that way.
I read it. It will work that way. The Democrats will control the Republican primaries in 2012. They will already have their candidate and many will reregister as Republicans for the primaries.It will probably be done pretty openly and the Republican Party orgs will cheer it. And, of course, the government media will be in full throat support for Romney until he turns into Hitler when he is actually nominated.
