No need to insert the "unless"
However, it is possible although improbable that Crist loses his primary.
What was the percentage that Alabama barely supported mixed-race marriages recently?
Only about 60% in a 2000 referendum to symbolically remove an anti-miscegination clause from the state constitution (long legally invalidated by those darn activist federal judges). About half of whites voted against the measure.
In 2004 there was another symbolic referendum to remove an anti-school desegregation clause from the Alabama Constitution which actually
lost. IIRC, like the mixed race marriage referendum this measure was overwhelmingly supported by black voters. Though in fairness some of the difference was that some of the far right (Christian Coalition, Roy Moore, etc.) mounted a campaign claiming that removing the post-
Brown v. Board of Education language not guaranteeing a public education as a right would open the door to federal lawsuits mandating Alabamans actually spend more than a pittance on their schools. Legal scholars widely derided these claims, but it was arguably enough to just barely put the no vote over the top.
Still, the 2000 referendum results show that there was (is) a broad racist voting block in the state. Good luck, Artur. You'll need it.
