The Washington Post‘s Chris Cillizza highlights another poll showing Senate Majority Leader Harry Reid to be no shoo-in for re-election in 2010:

Just 38 percent of voters had a favorable opinion of Reid as compared to 50 percent who had an unfavorable opinion in a Mason-Dixon poll conducted for the Las Vegas Review Journal.

Asked whether they were planning to vote to reelect Reid next fall or would vote to replace him, 35 percent said they would cast a vote for Reid while 45 percent said they planned to replace him. Another 17 percent said they would consider replacing Reid.

Of course, for these numbers to mean anything the Republicans first must recruit a credible challenger capable of beating Reid. Rep. Dean Heller is a possibility, but he is not well known statewide. Reid was nearly defeated in 1998 by John Ensign, the Republican who now holds Nevada’s other Senate seat, and Republicans sore about the strong 2008 Democratic challenge to Senate Minority Leader Mitch McConnell wouldn’t mind having Reid join the ranks of Tom Daschle.
