There are convincing reports that Democrats in both Michigan and Ohio took Republican primary ballots in order to vote for Rick Santorum, who had solicited their votes in Ohio. Since it seems unlikely that many Democrats actually prefer Santorum to Romney, they were probably being mischievous – trying to stick the GOP with a weaker candidate in order to make an Obama victory more likely.
What a high risk strategy! Just suppose it works, that Santorum becomes the Republican nominee for President. Then suppose that, as seems very likely, Greece defaults after all, and the European economy collapses, bringing on a second wave of the Great Recession. We might well find ourselves looking at President Santorum and several steps closer to authoritarian rule in America.
Democrats, be careful!
