Job security is always the primary job of our congress critters. In fact, when they're not sucking up face time on TV to convince their constituents that they're actually "working," they're on the phone making deals with major donors ~ selling the only thing they have to offer ~ favorable votes on legislation.
In fact, in case you haven't noticed, the only time they try to get chummy with their constituents is when it's close to re-election day. That's when they take off their jackets, roll up their sleeves and pretend they're just an Everyday Guy looking out for Mr. and Mrs. Joe Lunchpail.
It's a good gig if you and get it. The trick is to keep it.
