President Donald Trump and former President Barack Obama never went head-to-head for the White House, but now they are doing the next best thing. A handful of candidates they endorsed faced off in several big stakes elections on Tuesday.

There were at least 31 contests in which Trump and Obama have endorsed competing candidates. As of 11:15 p.m. EST Monday, 28 of them had been decided. Twenty-one went to Obama's candidates and seven went to Trump's.

Trump regularly handed out his endorsements via tweets. Nearly every tweet had the same message -- praising candidates for being strong on the Second Amendment, the border, the military, veterans and crime.

Obama, who did not jump fully into the midterm fray until early September, released his endorsements in a pair of "waves" on August 1 and October 1. His endorsements have also included several state level races, not just races for Congress and governor.

These are the positions Trump and Obama's endorsees were vying for, and who has won so far:

Arizona Governor

WINNER (Trump): Doug Ducey (R-Incumbent) def. David Garcia (D)

Since 1986, only one Democrat has been elected governor of Arizona.

California Governor

WINNER (Obama): Gavin Newsom (D) def. John Cox (R)

Newsom has been Lt. Governor since 2011

Colorado Governor

WINNER (Obama): Jared Polis (D) def. Walker Stapleton (R)

Polis is the first openly gay man elected as governor in the United States.

Connecticut Governor

WINNER (Obama): Ned Lamont (D) def. Bob Stefanowski (R)

Stefanowski is a businessman who has served as a CEO for General Electric and other companies. Lamont has tried running for office before. Most famously, he defeated U.S. Sen. Joe Lieberman in the 2006 Democratic primary. Lieberman kept his seat after running as an independent in the general election and winning.

Florida Governor

Ron DeSantis (R) def. Andrew Gillum (D)

The Florida Secretary of State ordered a recount on Nov. 10 after unofficial results showed DeSantis leading Gillum by 0.41 percentage points.

This is the seat being vacated by Republican John Kasich due to term limits.

Wisconsin Governor
