Comey is probably counting on a Hillary win, in which case he will be on good terms with the new administration. If Trump wins, he can resign and get a well-paying position at the Clinton Foundation.
If Clinton loses, her cash-flow is going to disappear. The reason for others giving her money will be gone...at least until Chelsea gets of age and experience to run for the senate.
The only position Comey should have, along with other convicted Clinton Foundation people, is hanging on the gallows.
