When Palin says it is.
You do realize that once she officially enters the race, the rules change. There are election laws, campaign finance laws, etc to consider.
Working as a free agent allows for a certain amount of freedom. Here's a word that might help you understand.... STRATEGY!
I have no idea what her game plan is and neither do you or anyone else for that matter. Do you think you could muster the courage to have a little patience and wait to see how her strategy plays out? Quite frankly, I find the whole thing fascinating but then I love folks who are able to think outside conventional paradigms. People like that are what's needed to restore our Constitutional Republic.
“And that date is?
When Palin says it is. “
So you dont know.
If she hasnt told you and you dont know, how do you know there even is a definite date?
“I have no idea what her game plan is”
Then why pretend you know her date to decide?
