I'd be happy to contribute time&money to an advert or two focusing on McCain's economic impact on Houston - especially the impact of his special advisors, Carly Fiorina and Phil Gramm.
Something like:
John McCain is ready to lose jobs and create even more economic devastation in Houston. McCain's campaign chair is Phil Gramm, the man who put special exceptions in the law for Enron while his wife was on the board (on the audit committee). While in Congress Phil also authored laws that lead to the creation of the market in those subprime mortgage backed securities and then he left congress and got a lucrative job with UBS which lost $19billion dollars last year. McCain's other economics advisor is Carly Fiorina - who got fired from HP after she got it to purchase Compaq leading to tens of thousands of lost jobs in Houston.
