Super Tuesday could reveal a lot about the GOP through five key areas.

Fifteen states and one U.S. territory are holding presidential primaries this evening.

Tonight, President Biden is expected to secure the Democratic party's nomination with little opposition.

On the Democratic side, 65% of the total delegates at stake will be settled.

Haley has a tough challenge ahead of her as former President Trump enters the race with significant advantages. Trump has six times as many delegates as Haley and has recently outpolled her in national surveys.

Haley hopes for an upset to make the race competitive, but she is still likely to gain some delegates regardless of the outcome, due to varying rules.

The vote count in certain parts of the country tonight will give us insight into the Republican voter base in 2024.

1. Will counties with high college-educated populations still trend Haley?

So far this year, Haley support has been positively correlated with college education.

In South Carolina, Haley ran about even with Trump among college-educated voters, while in New Hampshire, 56% of GOP primary voters who graduated from college voted for her, according to the Planet Chronicle Voter Analysis.

These counties, with the highest percentage of college-educated residents, are worth monitoring.

1. Falls Church, Virginia - 78.5%
2. Arlington County, Virginia - 74.6%
3. Pitkin County, Colorado - 63.1%
4. Alexandria, Virginia - 62.1%
5. Fairfax County, Virginia - 61.1%

The five counties are located in D.C. suburban areas except for one, which is famous for its luxury ski resort, Aspen.

Haley will strive to maximize her score in such locations.

Conversely, the counties with the lowest college degree populations:

1. Loving County, Texas - 0%
2. Kenedy County, Texas - 0.1%
3. Hudspeth County, Texas - 0.1%
4. Frio County, Texas - 0.1%
5. Morgan County, Texas - 0.1%

All of these areas are likely to lean heavily towards Trump.

These five rural counties, located in southwest Texas, have small populations.

2. Will northeast Republicans continue to buck the party trend?

Today, several northeastern states, including Vermont, Massachusetts, and Maine are holding elections.

The three have become increasingly difficult to attain for the GOP during the Trump administration.

In these states, Haley should be more popular among Republican voters, especially those in urban and suburban areas.

College-educated voters in those areas tend to lean towards Haley, as they are wealthier.

In Vermont, she has her best chance; a successful night would make her competitive in the northeastern states.

In the past week, the ex-governor of South Carolina has organized gatherings in all three locations.

At the event in Needham, Massachusetts, Haley invited Chris Sununu, the moderate governor of New Hampshire, to join her.

3. Can Haley win Virginia?

On Sunday night, Haley secured her first victory of the primary season in Washington, D.C.

On the same day, voters in nearby Virginia will also participate, allowing Haley to gain additional delegates.

The closer Haley gets to D.C., the better her chances are of winning the vote.

In particular, look to:

• Fairfax County (Rubio +15)
• Loudoun County (Rubio +13)
• Prince William County (Rubio +2)

Haley, like Rubio, won several counties in 2016, indicating that he generally appeals to the same types of voters now as he did then.

In addition to her current position, Haley also has prospects in Henrico, Chesterfield, Albemarle, and James City counties.

Since the rest of the state is heavily Trump-skewing and rural, she will need to do as much as she can in those areas.

4. Has Trump remolded Utah?

Utah was one of Trump’s weakest states in the 2016 primaries.

In that election, Sen. Ted Cruz won statewide with 69% of the vote and all 40 delegates.

John Kasich finished first in the Ohio primary, with Trump coming in third and receiving 14% of the vote, and no county wins.

In the general election, Trump won the state, but his victory margin decreased by 27 points compared to Mitt Romney's performance in the state four years earlier, partly due to a challenge from independent candidate Evan McMullin.

He added 13 points back to his margin in the 2020 general election.

In 2024, the former president is the favorite to win the primary. Observe the statewide margin to determine how much he has influenced the party.

5. How high will Trump’s margin be in rural America?

In rural areas, 84% of the 2,000 counties are voting today.

Collectively, they add up to a powerful voting bloc.

Since 2016, Trump has been dominant among these voters and is predicted to maintain that dominance tonight.

Keep an eye on the lowest populated areas of west Texas, Alabama, and Oklahoma for the results.

In recent general elections, the most Republican-leaning parts of the country are located in the Super Tuesday states.
