The U.S. Senate is likely going to see some changes. With long-serving members Pete Domenici (R-NM) and John Warner (R-VA) retiring, as well as the recent illnesses of Ted Kennedy (D-MA) and Robert Byrd (D-WV), some of the Senate’s traditional voices may be replaced with younger ones. Note: Kennedy and Byrd are both holding their seats.

Now with yesterday’s indictment of Ted Stevens (R-Alaska), another recognizable member may lose his reign in the Senate. He is currently in his 7th term as a Senator and is up for re-election in November. But first, he must triumph in the Republican primary on Aug. 26, where he is battling five opponents to hold his seat.

Other retiring senators include Wayne Allard (R-CO), Larry Craig (R-ID), and Chuck Hagel (R-NE). Republicans must defend 23 seats this November, Democrats only 12.

The combination of older members — the majority of which Republican — retiring, and the youthful energy of change accompanying Senator Barack Obama’s presidential bid, it is possible that fresh voices may take over the nation’s capital come November.

What impact do you think these retirements will have on the makeup of the Senate? What about on the makeup of Washington?
