Rep. Ron Paul’s presidential campaign strategy of targeting caucus states appears to have fallen flat — he is still without a win — and with only one caucus state remaining, it might appear time for him to withdraw.

But that is not how the Paul campaign rolls. Instead, the campaign is trying to pick up stray delegates in states that have already held caucuses.

Paul has secured 48 delegates, according to the Associated Press tally, making the total of 1,144 needed to secure the Republican nomination out of reach.
