Senator Christopher Dodd of Connecticut (upper photo) and Senator Harry Reid of Nevada (lower photo) are among the Democrats who face challenging reelection votes this year.
From a Los Angeles times report (see link below):
After losing the White House and nearly 70 congressional seats in the last two elections, Republicans are poised for a strong comeback in 2010, with significant gains likely in the House and a good chance of boosting their numbers in the Senate and statehouses across the country.
All 435 House seats, 36 in the Senate and the governorships of 37 states will be on the ballot in November.
Some of the Democrats' most prominent figures, including Senate Majority Leader Harry Reid of Nevada and Senate Banking Committee Chairman Christopher J. Dodd of Connecticut, are in serious danger as they seek reelection. Both would probably lose if elections were held today.
Last spring, Democrats seemed well positioned to add Senate seats. Today, a Republican gain appears more probable, costing Democrats their 60-vote supermajority and ability to stop GOP filibusters.
