No typos ... ever. If you're sloppy in what you send out from the start, the take-away for the reader is that you may be even more careless on the job.
Political affiliations. Never include them unless you're looking for a job that would benefit by disclosing this information and your level of participation. If it's irrelevant for your target, it may bias the reader unfavorably. The same goes for religious interests, participation in special-interest groups (gay or lesbian, for example), and certain social or service organizations.
Your age.The résumé should convey your potential to add value. The number of years you've been working tells the reader nothing about how good you are.
Marital status. It has no bearing on your qualifications or potential to add value immediately. It also feels hokey. In addition, by sharing this information, you open the door to lots of other questions that may border on illegal in making the decision about you as a candidate.
Reason for termination(s). Unless there's been a lot of movement or hopping on your résumé, there's no benefit to explaining the reason for a separation. Only do so if it enhances the story and provides critical information so as not to bias the reader against you (that is, due to no fault of your own, such as a downsizing, business elimination, a merger or closure).
