Love the phrase “tease campaign”.
As mid-to-end September nears, there will be more excuses as to why she hasnt announced. Now they start blaming FOX as if the contract with FOX is prohibiting her from running for President. Oct 31 is the last possible day, I believe. At the start of Oct, a number of Palin supporters will start looking towards that date and telling others how Reagan didnt announce until Nov, how she doesnt need to announce early, etc etc.
These fans need to understand she is in it for the money, nothing else. She is going to milk all sources until they run dry.
At this point I'm not even sure the "tease campaign" will end. I think she will announce she isn't running for the Republican nomination for president, which for her die hard supporters will leave them believing she might run 3rd party. Palin might even fan those flames by paying another visit to Trump. It's entirely clear she isn't actually running for President at this point and all the speculation has become completely silly.
