The U.S. now has a third political party — it’s called Trump.

Did you catch how President Trump repeatedly referred to his supporters at his Phoenix rally last week? Not as Republicans, but as the “movement.”

And the movement has no problem skewering Republicans and Democrats alike. As far as the Trumpites are concerned, the two political parties are species of reptiles inhabiting the same swamp in Washington.

Remember, Trump destroyed 15 credentialed Republicans on his march through the primaries. As president, he has brought in generals as his advisers, jobs that most presidents give to party insiders.

Trump’s open attacks on Republican Senate leader Mitch McConnell, House Speaker Paul Ryan and party veterans including Sen. John McCain just widen the gap between the GOP and the White House.

Where all this leads is anybody’s guess, which makes it all the more fascinating to watch.

The Colin Kaepernick saga is clearly not over — in fact, it’s expanding.

A demonstration outside NFL headquarters in New York the other day drew more than 1,000 people. Film director Spike Lee was on CNN backing the former 49ers quarterback for taking a knee during the national anthem. The NAACP requested a meeting with NFL Commissioner Roger Goodell to ask why Kaepernick is unemployed when white guys who couldn’t lead a touch-football team to the end zone are getting jobs.

All of this comes at a time when football, professional and otherwise, is losing some of its attractiveness.

More parents are steering their kids away from the sport, fearing they’ll suffer long-term brain damage from repeated blows to the head. Some high schools are abandoning their football programs because they can’t find enough students to play. NFL television ratings are suffering because of oversaturation — and, some think, audiences being turned off by players’ political protests.

Kaepernick’s apparent blackballing from the league may have opened the door for a real protest.

The movie “A Day Without a Mexican” illustrated what America would be like without its undocumented workforce. Well, what would happen if there was a day without blacks in the NFL?

Overnight, the league would find a job for Kaepernick.

Movie time: “The Hitman’s Bodyguard.” Ryan Reynolds and Samuel L. Jackson have hit up on what could be a gold mine of an action movie franchise. Gary Oldman makes the perfect bad guy, and with a ton of unemployed, bearded Eastern European extras — plus a surplus of cars, trucks, guns and torture equipment — I’m sure there will be more fun and games like this.

An alert: ABC’s popular “Shark Tank” program, where billionaires fund potential startups, has produced a possible 2020 Democratic challenger to President Trump.

Mark Cuban, the owner of the Dallas Mavericks basketball team and a savvy media communicator, could be just the guy, especially in a three-person race — Cuban the Democrat, Trump and a Republican nominee.

Great line overheard at Epic steak house at a fundraiser for the re-election of Sen. Dianne Feinstein: Former Assemblyman Rusty Areias, when someone asked him about Fresno Democratic Rep. Jim Costa’s knee-replacement operation.

“Why would a young guy (Costa is 65, but it’s all relative) need a knee replacement? He’s not an athlete — he’s not a runner.”

Areias’ reply: “He prays a lot.”
