“I believe that if we’re successful in this election,” President Obama told campaign donors in Minnesota last month, “that the fever may break, because there’s a tradition in the Republican Party of more common sense than that.”

Apparently Obama believes that if he wins this November, Republicans on Capitol Hill will all begin to act like Chief Justice John Roberts by betraying their conservative beliefs and signing on to Obama’s unprecedented expansion of the federal welfare state. But what would America look like if the Republican “fever” did break?

We already know. It would look a lot like the state of California, where no non-cyborg Republican has been elected governor since 1994. Democrats have also enjoyed complete control of the state legislature since 1997. And they have governed exactly the way you’d expect Democrats to govern.

Spending has more than doubled, from $45.4 billion in 1996 to more than $92.5 billion today. Income, sales and car taxes have all been hiked. As a result, California has the most progressive income tax system in the nation, with seven income tax brackets, and the second-highest top marginal rate.

Even with all those tax hikes, California’s 2012 budget is still $15.7 billion in the red. So what does Gov. Jerry Brown want to do? Raise taxes again, of course. He has proposed a ballot initiative that would: 1) raise sales taxes on everyone and 2) raise incomes taxes on those making more than $250,000 a year (like Obama has proposed to do nationally). But even this $8.5 billion tax hike would still leave the state $7.5 billion short. Where will California get that money? Who knows?

More.
