Studies divide over which offices are the best position from which to seek the presidency. This study looks at how candidates from various backgrounds perform in the competition for resources and votes in presidential nomination campaigns. The study also sheds light on Burden’s (2002)“candidate pool “and “candidate investment” hypotheses. As a group, senators are found to be relatively weak fundraisers, receive less campaign news coverage, and attract less public support than presidential candidates from most other backgrounds. Senators as a group are more variable than other groups of office-holders, but not significantly so. Most but not all senators who enter the race appear to invest themselves in their campaign.
