SACRAMENTO — There have been campaign rallies across the state on Proposition 6, the ballot measure to repeal the state’s 2017 gas tax increase. But none of them has been quite like the one planned for Sunday.

State Sen. Scott Wiener, D-San Francisco, says he’ll be wearing sensible heels and possibly a blond bob wig on a bike ride to oppose Prop. 6. It’s also a bike ride to poke fun at a comment by Diane Harkey, an Orange County Republican running for the 49th congressional district seat being vacated by GOP Rep. Darrell Issa.

Harkey supports the repeal of the 12-cent hike in the state gas tax and rollback of an increase in vehicle license fees, which the Legislature passed last year to raise $5 billion annually for road and bridge improvements and transportation projects. She explained her reasoning at a Yes on Prop. 6 rally the other day.

“This is just fraud,” Harkey said. “It’s forcing you to take bikes, get on trains, hose off at the depot and try to get to work. That does not work. That does not work with my hair and heels. I cannot do that and I will not do that.”

Wiener took to Twitter to call that nonsense — actually, he called it something else — and plans to join Emeryville Mayor John Bauters in organizing a hair and heels bike ride on Sunday at 2 p.m. starting from Market and Castro streets in San Francisco. The public is invited.

GOP candidate Diane Harkey (Orange County) supports Prop 6 (transportation funding repeal) b/c she’ll be forced to bike & take trains & “that does not work with my hair & heels.” Having ridden Muni w “hair & heels” & seen many drag queen ride bikes with the same, I call bullshit. https://t.co/CJRiLEnkNp — Scott Wiener (@Scott_Wiener) October 22, 2018

“You can wear a sensible wig and sensible heels and make it work on a bike or a train,” Wiener said. “It’s all about having the right attitude. But if the roads and trains are a mess because you don’t have the money to fix them, you’re going to have a problem with or without a wig or heels.”

Prop. 6 campaign leader Carl DeMaio, never one to shy away from a combative reply, urged the bicyclists to ride with caution.

“I hope those bikes don’t hit a bunch of potholes because politicians continue to divert gas tax money away from road repairs,” DeMaio said.
