Just ahead of next week’s midterm elections, the White House confirmed Monday President Donald Trump will be making another stop in East Tennessee in support of Tennessee Republican Senate candidate Marsha Blackburn.

The president will hold a Make America Great Again rally Sunday in Chattanooga, starting at 7 p.m. at McKenzie Arena, located at 720 E. 4th St. Doors open at 4 p.m. for general admission.

Blackburn and Democratic challenger Phil Bredesen have received the lion’s share of attention across the state, and a good portion of national attention, as they vie to replace retiring U.S. Sen. Bob Corker.

Currently, Republicans have a 51-49 lead in the Senate with the tie-breaking vote belonging to Vice President Mike Pence. Predictions of the Senate flipping have cooled a bit recently, but the seat is still vitally important to Republicans.

It is widely believed the Republicans' current majority in the House is in jeopardy as well. Election Day is Nov. 6.

Here are five things to know about the president’s visit this weekend:

1. Chattanooga not snubbed this time

Before Trump’s first visit to East Tennessee in early October, Bredesen and Blackburn had been scheduled for a debate in Chattanooga. The Trump rally was scheduled on the same day and Blackburn declined the invitation in favor of the Trump rally in Johnson City.

Bredesen still chose to come to the “Choose Chattanooga Ideas Forum.” He made it a campaign event.

At the time, former state Sen. and former Tennessee Democratic Party Chairman, Roy Herron, said Blackburn was “snubbing” Chattanoogans.

Well, that won’t be the case this weekend.

Blackburn has made it back to Chattanooga since the debate, at least once, and this time she’s bringing the president.

“Tennesseans from all walks of life support President Trump's agenda, and they are so excited he is returning to our state," Blackburn said in a statement. "We look forward to welcoming him back to Tennessee and having him on the campaign trail with us.”

Bredesen campaign spokeswoman Alyssa Hansen called Trump's visit a "perfect opportunity" for Trump to sit down with Bredesen to discuss their "shared interest in lowering prescription drugs prices."

"As skilled businesspeople, they can work together to get the best deal for Americans. Gov. Bredesen's plan to tackle prescription drug prices illustrates what he's said from Day 1 — he will work with President Trump to get things done for Tennesseans because that's what Senators ought to do."

2. Is Chattanooga bluest spot in East Tennessee?

Democrats in Knoxville consider East Tennessee’s largest city to be a blue dot in a sea of red, and it is. But Trump won Chattanooga’s Hamilton County by 16 points, easily his slimmest margin of victory in East Tennessee (still well above the nation as a whole).

However, travel just a few miles to the north, to Sequatchie County, where voters picked Trump by 60 points. To the East, in Bradley County, they picked him by 59 points and to the West, in Marion County, they picked him by 45.

So, while Hamilton County could be a tighter race for him next week, the area as a whole is safe territory for Trump politically.

This is in keeping with his other stops in the week leading up to Election Day: he is generally traveling to areas where he did well in 2016.

Hamilton County GOP Chairman Marsha Yessick said she's always concerned about election results until they start to come in, but she's confident in Blackburn's chances next week.

“I think she’s just got the message that people want to hear right now,” Yessick said. “She totally supports our president, Donald J. Trump, and she’s a conservative, she’s for the second amendment and for ICE and she’s going to be a great senator.”

Anthony Nownes, political science professor at the University of Tennessee, said the Senate race is unique because a Democrat actually has a chance. Any other Democrat in the state, he said, wouldn't be within 15 points of Blackburn.

“Republicans have dominated politics in this state for almost 20 years," he said. "The fact that Bredesen has kept it close is what makes this race unique."

Nownes said he would give the edge to Blackburn at this point, but nothing is guaranteed.

“I think the president and other Republicans are afraid," he said. "They think the House will flip. They are more confident about the Senate, but think it would be nothing short of catastrophic for their agenda if it flips. And while this is unlikely, it is not impossible … The president is trying to nail this down.”

3. Chattanooga's used to presidential visits

Johnson City was experiencing a presidential visit drought before the Trump visit – no sitting president had visited since Gerald Ford in 1976. Before that, it was Richard Nixon in 1970.

Not so for Chattanooga.

According to Chattanooga TV station, WRCB, the city has hosted six presidential visits, including four of the last five.

President Barack Obama came in 2013 to tour an Amazon facility. Before him, George W. Bush came in 2007, George H. W. Bush in 1992, President Ronald Reagan in 1987 and President Lyndon B. Johnson visited in 1964. Way back in 1940, President Franklin D. Roosevelt made an address at the Chickamauga Dam Celebration.

Vice President Joe Biden visited the city after four Marines were killed in the shooting of two military facilities in 2015.

4. Trump's a traveling man

The visit is Trump's third to the Volunteer State on behalf of Blackburn and his fifth to Tennessee since taking office in January 2017. Vice President Mike Pence also campaigned for Blackburn in Knoxville in September.

Ahead of the Chattanooga rally, Trump will be in Macon, Georgia — about 200 miles from Chattanooga — for a 4 p.m. rally in favor of Republican gubernatorial candidate Brian Kemp who is locked in a heated race with Democrat Stacey Abrams.

Nownes said Trump's last ditch stop in Tennessee probably won't move the political needle much, but could make a difference in a close race.

The president is also set to visit the Senate battleground states of Florida, Missouri, West Virginia, Montana and Indiana in the final week before the Nov. 6 election. Each are states that Trump carried in 2016 and where his approval rating remains strong.

5. Expect long lines at arena

The University of Tennessee Chattanooga’s McKenzie Arena seats 12,000 people – if Trump’s visit to Johnson City is any indication, plan to come early and wait in line because the arena will be filled.

Media reports of the long lines outside the arena in Johnson City were scrutinized by Trump opponents, but accurate. Thousands of people waited hours in line and didn’t get in the door.

Tickets to Sunday's event are free, but you must register for them online at donaldjtrump.com.

Doors open at 4 p.m. with the event scheduled to begin at 7 p.m.
