if you are to look at real life, at a normal job, people accept workers leaving their position to take another one to better themselves. The same goes for the political field. I feel most like when elected officials from their area go on to bigger things. I, for one, was disappointed in L. Madigan's recent statement she won't be running for gov. or sen.
But when you enter into a contract, in some cases, or a term, in this case, that you will be in this job for so many years before your evaluation by election, and instead quit - with no real calls for her removal from her constituents, but rather because she doesn't like the negatives of the job that go hand-in-hand, is a betrayal. She promised things and quit before she delivered them. Especially in a field of elected office, representing and working for the people, of which you are one, it is really absurd what she did. But she's the victim, I get it. She's crying all the way to the bank.
