Graham got those votes for many reasons...
1) The 17th amendment - outside money
2) Incumbency
3) many primary challengers splitting the vote
4) Open primary - dems help to pick your candidate
Knocking off a sitting Senator in a primary is NEARLY impossible even as awful as Graham is...
Don't worry about Graham, he only cares about one thing - keeping his Senate seat and staying in power.
He blows with the wind and the winds are blowing in a conservative direction.
Expect to see an new and improved Lindsey Ver 10.3 emerge after today.
FWIW, things would have been much different for Ol’ Lindsey if it were not for the release of the 5 Taliban big wigs from Gitmo.
This gave Lindsey a perfect chance to vocally oppose Obama and call for impeachment which played very well in his state.
