Senate Majority Leader Harry Reid is a powerhouse on Capitol Hill, but he may be undone by his constituents back in Nevada. If Republicans can put forth a viable candidate, a poll reveals that they have a good shot at taking his Senate seat. The poll finds that 45 percent of Nevada voters would replace Reid, with only 35 percent saying they would vote for him in 2010. It also finds that Reid has one of the lowest favorability ratings of any Senate Democrat. Nevertheless, Reid is not in any immediate danger, as no Nevada Republican has appeared up to the challenge of taking him on.
