Having solved all of our problems here in the Bay State — traffic, crime, taxes­, the T — Massachusetts politicians today are unveiling a billboard to fix the gun laws … in Florida.

According to a press release from the far-left anti-gun group Stop Handgun Violence, Massachusetts Speaker of the House Robert DeLeo, state HHS Secretary Marylou Sudders and Boston police Commissioner William Gross are expected to attend the unveiling of a new billboard attacking the “lax dangerous [sic] gun laws in Florida, particularly Florida’s lack of criminal background checks as well as unregulated and unrestricted access to assault weapons and high capacity ammunition magazines.”

The billboard compares Massachusetts’ restrictive gun laws to Florida’s, making the argument that, since Massachusetts has lower homicide rates, the Sunshine State should follow the lead of our local liberals and impose the gun laws of Cambridge on the people of Pensacola.

Which means that soon, people driving near the corner of Boylston Street and Dalton will be able to look up, see this billboard and say, “What the hell is that doing here?”

Seriously — is Speaker DeLeo expecting someone to take a wrong turn in Tallahassee and not turn around until they hit Tremont Street? And then, when they finally get back to the Gator state, they’re going to jump out of their pick-up and shout, “Hey, everybody — we’ve got to change our laws. Because those people in Boston said so!”?

When I shared this story with my friend and Florida politico Sarah Rumpf of RedState.com, she had an immediate response: “Go home, Yankee.”

Yeah, there is nothing Southerners love more than when arrogant New England know-it-alls tell them what to do. In fact, I think DeLeo and the gang should fly to Florida right now, get off the plane and loudly announce, “Hello, rednecks! We’re Boston liberals and we’re here to tell you what to do with your guns!”

Trust me, Bob: They’ll know exactly what to do with their guns.

John Rosenthal, the anti-gun activist behind this brilliant billboard stunt, is notorious for playing fast and loose with the numbers. This time last year he was pushing the shaky story that states with the most restrictive gun laws have the lowest crime rates.

But he’s right about Massachusetts and Florida. Florida’s 2017 homicide rate (5 per 100,000 population) was twice as high as the Bay State (2.5 per 100,000). So the argument is “Do what we do and you’ll have less crime, too!”

Interesting idea. But you know who has an even lower homicide rate than Massachusetts? New Hampshire! And you know what New Hampshire also has?

Why, pro-Second-Amendment gun laws very similar to Florida’s! New Hampshire’s gun laws are far more lax than Massachusetts’, and they had just 1 homicide per 100,000 in 2017.

And then there’s North Dakota, Idaho, Utah and Vermont. All with more gun rights, fewer gun laws and safer streets than Massachusetts. But you know what New Hampshire and these other states don’t have — and never will?

A bunch of blowhard politicians standing around a billboard lecturing us on what laws we should pass. Because unlike Massachusetts, they’re not awash in arrogant grandstanders who love nothing more than telling other people how to run their states, while their own citizens are stuck in nonstop traffic jams and paying ever-higher taxes.

Not that the Boston billboard is completely useless. “I think that billboard would actually look great in a TV ad in Florida,” Rumpf told me. “For Ron DeSantis, the pro-Trump Republican running for governor. He’d pick up 5 points overnight.”
