Imagine that you were elected to a federal office several years ago and had a safe seat with all the perks attached, including salary, expense account, and influence with corporate CEOs and other titans of industry. Suppose further that you knew that the future would be prosperous when you left office because the connections you made would make you a fortune as a lobbyist. Moreover, since unseating an incumbent is a herculean task, you felt that you were set for life.
In fact, as soon as you got elected, you began raising money and preparing for re-election. Governing and legislating became an afterthought – something you might engage in after your next campaign was carefully planned.
Suddenly, a guy runs for office with a lot of ideas about "draining the swamp" and making rules that include a prohibition on lobbying for at least five years after leaving office. As if that's not enough, he criticizes the "establishment" of which you are a significant part. To add insult to injury, this upstart comes from the private sector with no record of elective office, yet he has the audacity to run for the highest office in the land. You, and most of your colleagues, got where you are by starting in local elections, from city councils to mayor to state rep, and on to your currents spots at the national level.
You didn't take him seriously throughout his long and vociferous campaign, often refusing to endorse what he said and what he stood for. When he shocked the world with a strong win against a candidate the polls said would win easily, all you could do was feign approval and acceptance.
