The 2018 midterm elections are less than a day away. And if the final round of major national polls is to be believed, Democrats are poised to win control of the House of Representatives, while Republicans are set to maintain control of the Senate.

On so-called generic ballot polling, almost every survey shows likely voters support Democratic candidates over Republicans by an average margin of about 7.5 points. Just one of 13 major generic polls conducted in the lead-up to Election Day (Rasmussen Reports) gave Republicans an edge over Democrats, 46 percent to 45 percent — an advantage within the survey’s 2 percentage point margin of error. A CNN survey released Monday showed Democrats with a 13-point advantage over Republicans, an outlier that drew the ire of President Trump. But even a survey conducted by Trump’s favorite cable media outlet, Fox News, staked Democratic candidates to a 7-point lead over their GOP counterparts.

## Key races: Senate

Of the 35 Senate seats up for grabs on Tuesday, three high-profile races are seen as key to Republican hopes of maintaining their control of the chamber, perhaps none more so than in Texas, where incumbent GOP Sen. Ted Cruz is in a dogfight with Democratic wunderkind Beto O’Rourke. Polls show Cruz with a single-digit lead that is at or just outside the margins of error.

In Florida, the incumbent Democratic Sen. Bill Nelson is embroiled in a battle for reelection with Republican Gov. Rick Scott. Some polls show Nelson with a slight edge, others have Scott grabbing Nelson’s seat. A CBS News/YouGov survey has the pair knotted in a statistical tie.

And in Arizona, Democrat Kyrsten Sinema has a razor-thin lead over Republican Martha McSally.

## Key races: House

All 435 House seats are technically up for grabs on Tuesday, though several candidates — like Democrat Ayanna Pressley in Massachusetts — are running uncontested and are virtually guaranteed victories. But many races are tossups, including some in districts that weren’t expected to be close. In Iowa, Republican incumbent Steve King is in a surprisingly tight race against Democratic challenger J.D. Scholten. King’s comfortable lead has evaporated amid accusations of racist rhetoric and ties to far right extremists leveled against him by both Democrats and leaders of his own party. And polls in Kentucky and Virginia show Republicans and Democrats tied in two bellwether House races.

**Iowa’s Fourth Congressional District**

• New York Times/Siena College: Steve King (R) 47 percent, J.D. Scholten (D) 42 percent

Margin of error: +/- 5 percentage points

Edge: King +5

• Emerson College: Steve King (R) 51 percent, J.D. Scholten (D) 42 percent

**Virginia’s Seventh Congressional District**

• New York Times/Siena College: Dave Brat (R) 46 percent, Abigail Spanberger (D) 44 percentage points

Margin of error: +/- 5 percentage points

Edge: Brat +2

• Christopher Newport University: Abigail Spanberger (D) 46 percent, David Brat (R) 45 percent

Margin of error: +/- 4 percentage points

Edge: Spanberger +1

• Monmouth University: David Brat (R) 47 percent, Abigail Spanberger (D) 47 percent

Margin of error: +/- 4 percentage points

Edge: None

## Key governor’s races

Outside of the House and Senate, there are several hotly contested governor’s races to keep an eye on, especially in Georgia, where Democrat Stacey Abrams is vying to become the first African-American female governor in U.S. history. The race has drawn national attention, thanks in part to Oprah Winfrey and former President Barack Obama, who campaigned for Abrams over the weekend. Recent polls put the distance between Abrams and Republican Brian Kemp well within the margins of error, and both are polling below 50 percent. (If neither candidate reaches the 50 percent threshold, Georgia will hold a runoff on Dec. 6.)

The race for Florida governor has struck a similar chord nationally, with Tallahassee Mayor Andrew Gillum, like Abrams, fending off personal attacks from Trump. According to recent polls, Gillum appears to have a slight lead heading into Tuesday. And in Wisconsin, incumbent Gov. Scott Walker is facing a stiff challenge from Democratic Tony Evers. The most recent Marquette University survey has Walker and Evers in a virtual tie.

**Georgia**

• NBC News/Marist: Brian Kemp (R) 49 percent, Stacey Abrams (D) 47 percent

Margin of error: +/- 5 percentage points

Edge: Kemp +2

• The Atlanta Journal-Constitution: Stacey Abrams (D) 47 percent, Brian Kemp (R) 47 percent

Margin of error: +/- 3 percentage points

Edge: None

• Emerson College: Brian Kemp (R) 49 percent, Stacey Abrams (D) 47 percent

Margin of error: +/- 4 percentage points

Edge: Kemp +2

**Florida**

• Quinnipiac University: Andrew Gillum (D) 50 percent, Ron DeSantis (R) 43 percent

Margin of error: +/- 4 percentage points

Edge: Gillum +7

• St. Pete Polls: Andrew Gillum (D) 48 percent, Ron DeSantis (R) 46 percent

Margin of error: +/- 2 percentage points

Edge: Gillum +2

• NBC News/Marist: Andrew Gillum (D) 48 percent, Ron DeSantis (R) 43 percent

Margin of error: +/- 5 percentage points

Edge: Gillum +5

**Wisconsin**

• Marquette Law School: Scott Walker (R) 47 percent, Tony Evers (D) 47 percent

Margin of error: +/- 3 percentage points

Edge: None

• NBC News/Marist: Tony Evers (D) 50 percent, Scott Walker (R) 42 percent

Margin of error: +/- 5 percentage points

Edge: Evers +8

All of these polls, of course, should be taken with a grain of salt. While they were technically within their margins of error, most national surveys conducted on the eve of the 2016 presidential elections showed Hillary Clinton with a narrow lead over Trump. Clinton wound up winning the popular vote, finishing with 65,844,610 (48.2 percent) compared with Trump’s 62,979,636 (46.1 percent). But Trump finished with 306 electoral votes to Clinton’s 232 to capture the presidency.
