A labor source confirmed to TPMDC tonight that the AFL-CIO voted to back new Senate candidate Lt. Gov Bill Halter over Sen. Blanche Lincoln in the May 18 Democratic primary in Arkansas. Three unions within the umbrella group have committed to a $3 million independent expenditure on Halter's behalf.
Halter enters the race with strong financial backing, but without a lot of time to campaign. The primary election is scheduled for May 18th, giving Halter just 11 weeks to run against Lincoln. With many political observers believing that Blanche Lincoln is the incumbent senator most likely to lose in the general election, the Arkansas Democratic primary will probably be one of the most closely watched primary elections this season.
