Optimism is dwindling for a local Tennessee Senate candidate who had hoped provisional ballots might bridge the 34-vote gap between him and apparent Democratic Primary winner Jim Lewis.“From a poll I did of the other six counties in our senatorial district, the numbers just aren’t there even if each provisional ballot was a vote for Steve Roller,” said Warren County election administrator Donna Yates. “There just aren’t enough votes there.”After last week’s election, Roller trailed Lewis by 34 votes. Lewis earned 2,935 votes in the seven-county district, while Roller claimed 2,901.
