Quin Hillyer on Elections 2002 -- National Review Online

As recently as October 10, the GOP looked poised to regain control of the Senate and at least maintain its six-seat edge in the House. Now, though, the Senate contest looks like an even battle, and the House majority itself may yet slip away.

All of which means that, under the leadership of a hugely popular president, this should be a year of big Republican gains. Instead, though, look for Republicans to struggle. Control of the House may not be apparent until late into the morning after election day; the final Senate lineup may await decisions of potential party-switchers and the results of a Louisiana runoff on December 7.

And don't be surprised if enough elections are close enough that federal courts again are called in to referee.

The best conservative national election forecaster, who had correct party split predictions for the House and Senate in 1998 and 2000, is worried and thinks the results may not be known immediately.
