A good first step would be to eliminate separate security lines for First Class/VIP and everyone else. I suspect security lines would end up being shorter if our elected officials had to go through exactly the same process as the rest of us.
As a hack, just go through the first class line regardless of the class you're flying in. I know several people who do this, and none have been questioned about it. The obvious response is: "Why should paying the airline more money get people better treatment from the Federal government?".
In my experience this works every time at Dulles international (IAD) but never works at Hartsfield-Jackson Atlanta International (ATL). At ATL you get sent to the back of the normal line.
The hack is to print FIRST on your boarding pass. The person checking whether or not you are allowed in the priority line does not have access to the reservation system to check that you are actually in first class. You keep your real boarding pass in your pocket and show that to the TSA and gate agent.
Note: untested. I get to use the first-class lines anyway :P
