Senator Obama has a number of issues he should be hammering on to highlight how extreme McCain, Palin and indeed the entire Republican party have become.  Here are the themes of some ads I'd run, if I were sitting on Obama's war chest:

1 -- Palin, and today's Republican party extremists, wants to make it illegal for your daughter to even get the morning after pill, even when raped. Is this "small government," or is this the government legislating one person's extreme religious views for everyone?

2 -- McCain, and today's Republican extremists, wants to bankrupt social security by diverting the money budgeted for social security benefits into privatized accounts, leaving people who've paid social security taxes for decades with nothing for retirement.

3 -- McCain and today's extremist Republican party want to destroy the one part of today's health insurance system that actually works -- group health insurance, by increasing taxes on companies that provide health insurance to their workers.  Individual health insurance is an oxymoron -- real insurance means spreading risk among a large pool of people, not making people pay their own medical bills.  McCain just doesn't understand the fundamentals of insurance, and can't be trusted to design a new insurance system.

4 -- Governor Palin can't seem to remember the truth -- she first said that no one in her administration had anything to do with "troopergate," and then had to announce that her chief of staff intervened. As apparently did her husband as well. She continues to claim that she refused money for the bridge to nowhere, even though she first lobbied for it, then accepted the money and spent that money on other projects only when the bridge itself got too bad a public reputation.  She claims to be a reformer in favor of small government, but she really stands for taxing everyone to give money to a few.
