Candidates can't do email.

Patrick Ruffini sent me to a wonderful, wonderful study examining the email strategies of the six major candidates this year (Obama, Clinton, Edwards, Huckabee, McCain, Romney). The results are not encouraging. The candidate who used email the most effectively was...

...71 year old John McCain.

The Results
After examining the email programs and grading each candidate, 24 total points equaling a perfect score, no campaign's email program received a passing grade.

Here is the final tally:

While Sen. McCain scored the highest of the six with 16 points, each candidate's campaign missed multiple opportunities toward full email optimization. As the election steamrolls through the summer toward Election Day in November, each of the remaining candidates needs to critically look at his or her campaign and make sure each marketing effort, including email, is being maximized to its full potential

I suggest checking the study out.
