There are a couple of things I like about Washington, D.C.

The first is that when you're driving around there you can hear C-SPAN radio replaying all the important morning political talk shows at any time of the day or night.

The second is ... I forget. Let me think. Maybe it will come to me.

In the meantime, let me describe something I heard on the car radio Sunday. It was an interview with Chris Wallace of Fox News in which Mitt Romney went after Donald Trump with a fervor that he never employed against Barack Obama in 2012.

One of Romney's attacks focused on the Donald's business career. He advised the listener to "look how many small people he crushed along the way."

That takes nerve coming from a guy who was attacked by his fellow Republicans in 2012 for being a "corporate raider" who fired "tens of thousands of Americans."

Then there's Romney's allegation that Trump is a "a phony" and "a fraud." In 2012, Romney ran on a platform of repealing Obamacare - even though it was "the same f-ing bill" as the 2006 Romneycare plan in Massachusetts, according to the MIT professor who helped design both.

Only inside the Beltway can a politician get away with this sort of thing. On the sane side of I-495, Romney has zero credibility with Republican voters.

The consensus at the annual Conservative Political Action Conference I attended last week was that Romney's attacks were actually helping Trump.

Those attacks also seemed to be hurting the guy who represents the establishment's last hope of stopping Trump. That's Florida Senator Marco Rubio, who spent most of his CPAC speech Saturday taking shots at the Donald.

As Rubio was speaking, Republicans in four states were busy rejecting his candidacy and delivering their delegates to Trump and Texas Sen. Ted Cruz.

But there's always his home state. "I can tell you this: we will win the state of Florida," Rubio proclaimed.

The polls say otherwise. Trump's got a comfortable lead there and in the other big primary a week from today in Ohio. That's the home state of the other establishment endorsed candidate in the race, Gov. John Kasich.

Kasich, who barely registers in the delegate count, said at CPAC that he's hoping to stick around till the convention in the hope that Trump won't get the 1,237-vote majority needed to secure the nomination on the first ballot. A floor fight is the only way he or Rubio could get the nomination, he admitted.

But by sticking around, they're making it easier for the Donald to win the nomination by splitting the other-than-Trump vote.

At the moment, Trump's beating Cruz by just 384-300. If those other two had dropped out, the race might be even at the moment.

But so far the delegates have been awarded on a proportional basis. As of next week we start seeing winner-take-all contests.

That means that if Trump gets the 36 percent result predicted in the latest Monmouth University Poll of Ohio, then he'll get all 66 of that state's delegates.

The same goes for the 38 percent Monmouth predicts Trump will get in Florida. That would get him all 99 delegates in the divided field.

No wonder Romney and the rest of the establishment types sound so desperate.

One decidedly anti-establishment Republican from New Jersey, arch-conservative Steve Lonegan, said that by sticking with Rubio the establishment is inadvertently helping Trump.

Lonegan, who's working on the Cruz campaign, said his man needs to win 58 percent of the remaining delegates.

"Rubio is basically blocking a pathway to victory for Cruz," said Lonegan. "That victory is doable if Rubio got out of the race."

But if Rubio and Kasich keep fragmenting the other-than-Trump vote, then the Donald could pile up big numbers in the winner-take-all races to come.

That wouldn't bother another of New Jersey's leading conservatives. Republican state Sen. Mike Doherty of Warren County was an early backer of Trump .

"Donald Trump has already done a great public service," said Doherty. "He prevented a third Bush presidency. He should get all the accolades."

And even if Trump doesn't win, Doherty said, the establishment will be thwarted in its attempt to put in a compliant candidate like Rubio.

"If it can't be Trump, let it be Cruz. Either way, it's a huge improvement," he said. "The only way the establishment wins is if we have a civil war at the convention."

But that's not likely. Even if neither gets a majority, those Trump and Cruz delegates would never support the sort of candidate the establishment wants, he said.

Oh yeah, that reminds me of the other thing I like about Washington:

It doesn't always get its way.
