For those keeping score, as of today, there are 28 Republicans and 5 Democratics who have announced they will not seek reelection for the House of Reps.
Three of the Democrats (Udall, Udall, Allen) and two of the Republicans (Tancredo, Heather Wilson) have given up their House seats to run for Senate seats (CO, ME, NM).
This is the highest number of Republicans to retire from the House in more than 40 years.
The reason for some is obvious - corruption investigations.
Any thoughts on why the rest are stepping down?
