Go into the polling booth and put a cross next to Jesus's name?
As Bill Hicks once said 'Do you think if Jesus came back, he's going want to see a fucking cross?'
I think it'd be hilarious, I'll put a cross by his name, just to watch the RAAAGE when the religious right realise that their very own figurehead is totally fine about gays, thinks we should look after the sick, the poor and the needy, (more welfare/healthcare/etc) and hates corporate America (turning over the tables of the money lenders.) I could also see him cutting the defence budget back to almost nothing and setting the army working on rebuilding the poorer parts of America instead.
He could also do the catering, free glass of wine and a Filet'o'Fish when you Vote for Jesus.
