In a statement just out from Ron Paul's campaign, the Texas congressman announces that while he'll continue to try and accumulate delegates at state conventions, he won't be mounting a serious effort in new upcoming primaries:
We will continue to take leadership positions, win delegates, and carry a strong message to the Republican National Convention that Liberty is the way of the future.
Moving forward, however, we will no longer spend resources campaigning in primaries in states that have not yet voted. Doing so with any hope of success would take many tens of millions of dollars we simply do not have. I encourage all supporters of Liberty to make sure you get to the polls and make your voices heard, particularly in the local, state, and Congressional elections, where so many defenders of Freedom are fighting and need your support.
I hope all supporters of Liberty will remain deeply involved - become delegates, win office, and take leadership positions. I will be right there with you. In the coming days, my campaign leadership will lay out to you our delegate strategy and what you can do to help, so please stay tuned.
Paul's campaign has spent money to air television ads in his home state of Texas, which votes at the end of May, and that effort has apparently come to an end. It's an original way of announcing that a presidential campaign is over, but that's what the statement amounts to.
