2010 United States Senate election in Arkansas

Incumbent Democratic Senator Blanche Lincoln ran for re-election to a third term, facing a strong primary challenge from Lieutenant Governor Bill Halter and prevailing only in a runoff.

[2] MoveOn.org supported Halter, criticizing Lincoln for her stance on issues such as health care and environmental regulations.

The results were as follows:[25] Arkansas had previously only elected one Republican senator since the Reconstruction, Tim Hutchinson who was defeated after his first term in 2002 by Mark Pryor.

RealClearPolitics claimed that in 2010 Lincoln had the potential for the lowest percentage of the vote for any incumbent since the nation first began directly electing senators.

[32] Boozman received 58% of the vote in the general election and defeated Lincoln (37%), Independent Trevor Drown (3%) and Green John Gray (2%).
