The question shouldn't be "do petitions work?" but "how do they work best?" It's all down to the power of a strong personal story that will help you build an army of supporters who you can call on to take action, every step of the way to victory. If you do that, your campaign will be impossible to ignore - however many signatures it attracts.
In my new political incarceration as a 'striver' I am angry. I got out of bed this morning knowing that there is nothing that my company, the people I work with or many of our clients can do. I feel stupid in the knowledge that the decks are stacked against us, we are not on a level playing field and their is nothing we can do.
