The Note: More than a divided court in the balance Now it’s really on – and then some, and then some again.

The TAKE with Rick Klein

Now it’s really on – and then some, and then some again.

The battle for Justice Anthony Kennedy’s swing seat on the Supreme Court will play out with different rules governing a familiar game. The man now at the center of this fight relishes the combat, doesn’t care about the old rules anyway and knows he’s facing down opponents with few good options.

It’s trite to say the stakes could not be higher, but it’s true. There’s enough justified concern out there to make the battles of the last 18 months seem like warm-up acts for a hot summer.

It’s also trite to say that elections have consequences, but that’s also true. President Donald Trump gets to make this choice, and he has a GOP Senate majority — and a worried crop of red-state Democrats up for re-election — to ratify his choice, barring something unexpected.

The Democrats have a waking nightmare along with a bad hand that they could play into something worse. What may help their chances in House races may hurt them in the Senate, with an already restive base primed for the fight of all fights with Trump on any number of fronts.

It all means more tensions or worse for a divided nation. Much more than a divided court is in the balance.

The RUNDOWN with John Verhovek

Republicans had their eyes set on the U.S. Senate seat held by North Dakota Democrat Heidi Heitkamp long before Donald Trump ever came on the political scene, but last night the president wasted no time in joining the party's pile-on.

"You need a senator that doesn't just talk like they’re from North Dakota, you need a senator that votes like they're from North Dakota," Trump said Wednesday night in Fargo alongside the GOP nominee running against Heitkamp, Rep. Kevin Cramer.

Heitkamp, who often touts her working relationship with Trump, is one of 10 Democratic senators up for re-election in 2018 in states he won in the 2016 election, and the wily politician wasted no time in casting the president's visit as a plus for the state, while maintaining her own political independence.

"I don’t answer to a political party or president, I only answer to North Dakotans who deserve an independent voice in the Senate," Heitkamp said in statement sent out immediately after the rally. "That’s why I’ve always been eager to work across the aisle – including with the president — to get results for our state, and today’s rally hasn’t changed that."

Cramer played up his standing as a stalwart Trump ally, pledging to be with the president "100 percent" at every turn.

The race is a classic collision of national trends and local politics, especially when it comes to Trump's tariff policy, a policy that he defended Wednesday night but weighs heavy on the state's large farming population.

Last night showed the race will no doubt be a political rollercoaster all the way through November.

The TIP with Alisa Wiersema

Although President Trump has yet to announce his second Supreme Court nominee, his unknown pick is already becoming a campaign topic in the Indiana Senate race.

Drawing party lines in a red state Trump won by nearly 20 points, Republican Senate nominee Mike Braun is predicting his opponent across the aisle, incumbent Sen. Joe Donnelly, will support whomever Trump nominates. But the prediction comes with an allegation that could reflect the nation’s partisan divide — in a statement, Braun says the red-state Democrat will support the president’s choice because "it's an election year.”

"I expect Senator Donnelly to vote for President Trump's nominee to distract from his liberal record," Braun said in a statement. "Hoosiers won't be fooled by Senator Donnelly's election year pandering."

As one of a handful of moderate Democrats in the Senate, Donnelly has voted with Trump 62 percent of the time — including being the third Democrat to back Justice Neil Gorsuch at the time of his nomination.

Ahead of November, Donnelly has not indicated immediate early support for the future Supreme Court hopeful.

"Part of my job as a United States Senator is to carefully consider the president's judicial nominees, including for the Supreme Court," Donnelly said in a statement. "I will thoroughly review the record and qualifications of any nominee presented to the Senate."
