ELI5: Why don't politicians get sick more often considering they have to shake thousands of strangers' hands every election cycle?

You would be amazed how effective washing your hands before you eat anything or touch your face can be. 

To this, washing is more effective than hand sanitizer because many bugs you don't want to catch are transmitted by spores. Washing removes all the germs by the simple action of soap, you don't need special antibacterial soap on top of that. Why worry about killing what is not on your hands anymore with a toxin that the bugs get resistant to?
