Next up for Jerry Brown — try to reform Prop. 13

My cousin the governor, Jerry Brown, ran like a marathon man to pass his tax plan. Might I suggest that his next bold move be to enlist Warren Buffett for a joint effort to reform Proposition 13?

Between Brown’s brains, Buffett’s billions and the Democrats’ likely supermajority in the Legislature, I’m sure they could get something done.

Now that would a legacy.

It’s time to hand out kudos — and aspirin — to state Assembly Speaker John Pérez and Senate President Pro Tem Darrell Steinberg.

Kudos for winning a Democratic supermajority in both houses, assuming the preliminary results of a

couple of close races hold up.

Aspirin for the headaches they’ll have when the infighting starts, which by my calculations will be the day after everyone is sworn in.

Take it from someone who has been there — the first thing Pérez and Steinberg need to do is get very friendly with about five Republicans who just might vote their way in a pinch.

They can think of it as insurance for the five fellow Democrats who will most certainly double-cross them somewhere down the line.

San Francisco is about 9 percent Republican, and the way things are going, the rest of California may soon be that way as well.

Talk about turning blue. Democrats already hold every statewide office, they’re on the verge of total control of the Legislature, and they picked up three seats in the state’s House delegation Tuesday. Meanwhile, Republican voter registration has dropped below 30 percent.

The only way for the state GOP to regain any semblance of relevance will be to part ways with the Tea Partiers. One look at how lunatic-fringe candidates cost the Republicans Senate victories in red states Indiana and Missouri tells you how badly the party needs moderates.

Get back to the middle, at least on social issues, and Republicans will find that many Latinos — crucial to President Obama’s winning coalition — are not naturally on the left side of the dial.

One overwhelming election victor: San Francisco Mayor Ed Lee.

All his measures on the ballot — money for parks and City College, a housing trust fund, business tax reform — won hands down. He even kept that eco guy from Marin from moving forward on draining Hetch Hetchy.

True, Lee’s appointee to the Board of Supervisors, Christina Olague, got trounced. But that was partly because she crossed him during the Ross Mirkarimi affair, and partly because the woman who beat her, London Breed, is a rising star.

If I were one of the other three supervisors who voted to keep Mirkarimi as sheriff, I would really be worried about my own job — or the one I had hoped to get elected to down the line.

The newcomers to the Board of Supervisors will make for an interesting vote when it comes time to pick the next board president.

I hear former Supervisor Chris Daly is trying to play kingmaker on behalf of the unions, so it really ought to be fun over the next several months down at City Hall.

Sen. Dianne Feinstein’s victory party was great fun. No dancing, but she did make extra room for all the walkers.

To Molly Munger — we really should talk. Having spent something like $40 million to get 28 percent of the vote for your education tax plan, you should be entitled to pro bono legal representation for your lawsuit charging political consultant malpractice.

Movie time: “Flight.” Denzel Washington flies upside down in more ways than one, as an airline pilot caught in a dilemma of his own making.

I don’t see an Oscar on the horizon, but it’s still worth catching. Don Cheadle does the usual Don Cheadle act, this time as a crafty lawyer.

See it before it flies out of town.

The day after the election, I was walking up Sansome Street when this homeless guy says to me, “Mr. Mayor, baseball season is over. You know what that means?” “No.” “We don’t need a Mitt anymore.”

Congratulations, Mr. President. Your re-election has done what many people said could not be done — remove forever the question of whether a brother could get to the White House and stay there.

Your opportunity to lead this nation is now signed, sealed and ready for you to deliver on it.
