Republican strategist predicts his 2020 Dem primary final four

Republican strategist Ford O’Connell said he thinks the 2020 Democratic primary will come down to four candidates.

“I’m sure I’m going to take heat for this several months for now,” O’Connell told Hill.TV during an interview on “Rising" as he unveiled his Democratic final four.

“I think when it comes to the Democratic Primary you’re actually down to four people and that is the three B’s and Kamala HarrisKamala Devi HarrisJulián Castro: Trump should be impeached for trying to obstruct justice 'in very concrete ways' Poll: Buttigieg tops Harris, O'Rourke as momentum builds Trump Jr. slams 2020 Dems as 'more concerned' about rights of murderers than legal gun owners MORE: Biden, Beto and Bernie,” he continued.

O’Rourke entered the race last week and is already sparking controversy after he said in a Vanity Fair interview that he was “just born to be in it.”

“I have a lot of respect for Beto and it’s great to have some Texas in this race,” Klobuchar told NBC host Chuck Todd. “I wasn’t born to run for office, but I am running.”

O’Connell told Hill.TV that O'Rourke nevertheless poses a "true threat" to some left-leaning candidates like Sanders.

"Clearly Bernie sees Beto as a true threat, they seem to be fighting over the same turf based on how I’m watching the opposition research within the Democratic Party," he said.

While O’Connell said the Texan shouldn’t be written off as a contender, he predicted that O'Rourke would instead likely be the running mate of the eventual nominee. 

“When someone raises $6 million in 24 hours, I can’t sneeze my nose at them,” the strategist said, referring to O’Rourke’s massive fundraising haul that came from more than 128,000 donors.

“I see Beto going off most likely being the VP nominee when you start looking at the age difference,” he added.
