This is a deliberate DNC/Soros strategy, which was developed last year to try and split the GOP vote by using fake TEA Party candidates and websites.
This operation's first "alert" was spent on trashing Palin's forthcoming movie, and remarks made about her special needs child. If you try to find out who is behind the "National Tea Party Alert", you can't. It is registered to "Domains by Proxy."
Just wanted you to be aware for future references/articles.
