Senate Majority Leader Harry Reid is increasingly looking like one of the most vulnerable Senate Democrats in the 2010 election cycle. A new Mason-Dixon poll shows both Republican challengers (former state party official Sue Lowden and real estate developer Danny Tarkanian) beating Reid in hypothetical matchups:
In one general election scenario, 49 percent of respondents picked Lowden and 39 percent chose Reid. In another, 48 percent picked Tarkanian to 43 percent for Reid. That poll, which surveyed 500 voters Tuesday through Thursday, has a margin of error of plus or minus 4.5 percentage points.
The primary electorate is closely divided on who they want to challenge Reid, with 23 for Lowden, 21 percent for Tarkanian and 44 percent undecided.
