Seats in Congress set Tuesday

WASHINGTON —The Census Bureau on Tuesday will announce the winners and losers in the reapportionment sweepstakes.

Some states will gain a congressional seat or two, based on their populations, while others could lose one.

Kansas will likely remain unscathed and retain its four seats in the House of Representatives.

Next-door neighbor Missouri, however, is on the bubble and could see its nine-member delegation drop to eight.

Every 10 years since 1787, the Census has determined how many House seats each state will have. It's called apportionment. The 435 seats in the House will be divvied up among the 50 states based on population figures collected in the decennial census.

Republicans are expected to gain overall because of population shifts. They also control more state legislatures, where the new congressional district maps for most states will be drawn in time for the 2012 election.

While reapportionment is based on the one-man, one-vote rule, politics overshadows the process.

"It could create open warfare," said David Wasserman, a congressional analyst at the nonpartisan Cook Political Report. "Every round of redistricting features games of musical chairs."
