Redistricting is a time for stock-taking, for looking back and looking ahead.

State legislators who've been around a while are suddenly faced with the often stark reality of signing on for another 10 years. They add a decade to their current age and wonder if they want to be in the game that much longer.

Some decide to stick with it for just one more election so they can make extra sure their party holds their seat.

Some decide to retire right away, figuring their party has drawn the map solidly enough to ensure a suitable replacement.

Legislators in the minority party are far more likely to be mapped in with fellow party members and then discover that they don't want to face the prospect of running in a primary, so they retire.

Others decide to use the opportunity to move up the political ladder. The congressional districts were redrawn, which gave state Senator Dave Koehler (D-Peoria) a possible opening. He took it.

If history is any guide, we're likely to see a raft of retirement announcements in the next few days, weeks, months and even years.
