We need to get behind 1 challenger so that Linsthy cannot divide and conquer.
No, we don't. From the article ......
South Carolina is technically a runoff state, so if the challengers work together to keep Graham under 50 percent, they can get to a runoff election with the candidate who comes in second challenging Graham. Conservatives point to Sen. Ted Cruz (R-TX) and his election in Texas as an example of the model they plan to use to win. Cruz technically lost the primary to Lt. Gov. David Dewhurst, the establishment's pick for U.S. Senate, but he won in the ensuing runoff.
Guess you're not from South Carolina.
Here's how our primaries work:
Voters who voted in a party's primary, can vote only in the runoff of the same party. Voters who did not vote in the primary, may vote in either party's runoff.
The primary is for Democratic and Republican candidates only. Candidates running unopposed for their Party's nomination will not appear on primary ballots.
Voters may not vote in a political party's runoff if they voted in another political party's primary. However, voters who did not vote in either politicial party's primary may vote in either politicial party's runoff.
A defeated primary candidate may not actively offer or campaign as a write-in candidate for the ensuing election. The use of posters or stickers on the ballot is not permitted. The voting machine provides for a voter to write-in a candidate. Write-in votes are not allowed in primary elections or the election of President or Vice-president.
While the state permits fusion (a candidate may be nominated by multiple parties), if a candidate runs for and looses a primary (of any party), the candidate cannot appear on the November ballot.
