Rep. Ron Paul’s campaign has been sending its supporters into state GOP conventions to fight for slots as delegates to the Republican National Convention in Tampa. This weekend, they had success in Nevada and Maine.

In Nevada, Mitt Romney had won the state’s February caucuses with more than half the vote. But Mr. Paul’s supporters nonetheless captured a majority of the delegate posts, which were assigned at the state convention this weekend.

Of the state’s 28 delegates to be sent to Tampa, 22 are known Paul loyalists, the Las Vegas Sun reported.

State GOP rules require many of these Paul supporters to vote for Mr. Romney to be the party’s presidential nominee on the first ballot at the convention, reflecting his win in the caucuses. If there was a second ballot—and few expect there will be—these delegates could then vote for Mr. Paul.

In Maine, local media reported that Paul supporters wrested control of the state GOP convention and claimed a majority of delegates, though it was Mr. Romney who had won the party’s caucuses in February. Mr. Paul appears to be doing well in Iowa, as well.
