McCaskill leads Senate challenger support poll, needs your help to stay there

Sen. Barbara Boxer's PAC for a Change is asking for your vote to help determine which Democratic Senate challenger will get its financial support. Three days ago, Bob Casey in Pennsylvania had a huge lead in the poll, but Claire McCaskill has since surged from well behind at 7% to take the lead by one percentage point over Casey (17% to 16%). 

McCaskill needs your help to gain the support she needs to fight a tightly-contested race. The poll ends on July 21. Make sure to vote, and to spread the word to friends and family.
