Former Members Dick Armey. Tom Daschle. Tom Foley. Trent Lott.
Once, these politicos ranked among Congress' most powerful members. Today, they share another distinction: They're lobbyists (or "senior advisors" performing very similar work). And they're hardly alone. Dozens of former members of Congress now receive handsome compensation from corporations and special interests as they attempt to influence the very federal government in which they used to serve.

This is an incomplete list of just one body of lawmakers who went to work for just one industry. It's a very limited reference to the much, much larger whole.
>If a legislator agrees with you, you want to keep them
Although I included people tied to legislators (and their interests) you opted to limit your response to just legislators and even that seemed more platitude than substance.
> Also, campaign donations are capped at like $5000
So what? This falsely implies no donor can get more than $5k into any one campaign fund. Tossing it out there as primarily defining detail seems disingenuous. It omits non-cash contributions. It omits donations to traditional PACs, Super PACs, 527s, political parties, 501(c)4,5 & 6.
It omits all the possible avenues of getting money to candidates that someone with a CapHill political background almost certainly knows.
It does dovetail nicely with an alternate narrative about revolving doors not existing, however.
