President Donald Trump is on a roll.
His meeting with G7 leaders played well with his base, who see the president as putting America's economic interest first. And he's coming off from a historic summit with North Korean dictator Kim Jong-un that could lead to a denuclearization of that rogue nation and almost certainly has brought us back from the brink of war.
That-which should be seen as a good thing all around-has earned some criticism from the left, but more praises from those who aren't all that keen on the president.
It looks like his actions and message are playing well with the GOP voters, too.
Tuesday saw primary elections in Maine, South Carolina, Nevada, North Dakota and Virginia.
Many GOP contests went the president's way, including the Senate nomination of Trump loyalist Corey Stewart in Virginia, who will face U.S. Sen. Tim Kaine, Hillary Clinton's running mate in 2016. That should be interesting.
The big news, though, was in South Carolina, where incumbent Republican U.S. Sen. Mark Sanford went down in flames, losing the nomination to challenger Katie Arrington, who has supported President Trump the whole way.
Sanford has been a frequent critic of the president and, as we all know, the president doesn't take well to that.
So late Tuesday, President Trump took to his favorite platform, Twitter, to endorse Arrington-and take a few shots at Sanford-including a reference to an extramarital affair with a woman in Argentina while he was South Carolina's governor.
"Mark Sanford has been very unhelpful to me in my campaign to MAGA. He is MIA and nothing but trouble. He is better off in Argentina. I fully endorse Katie Arrington for Congress in SC, a state I love. She is tough on crime and will continue our fight to lower taxes. VOTE Katie!" the president wrote.
The Tweet is likely not the only reason Sanford lost, but it definitely had an effect.
"We are the party of Donald J. Trump," Arrington said after the results were announced.
Democrats have been hopeful for a "blue wave" in November's general election that would give them control of the U.S. House of Representatives and Senate.
We'll have to see what happens, but considering this week and California's primaries last week, the Republicans have been nominating solid candidates that their voters can get behind while the Democrats have been divided by infighting and putting up contenders who most likely aren't.
The vaunted "blue wave" might well peter out before it reaches November's shore.
