While Ramaswamy clearly tried to differentiate himself from Scott on the question of unions, Pence glossed over his primary challengers and shifted directly to the general election, calling for repealing the Green New Deal and criticizing Biden.

According to a September poll by ABC News and The Washington Post, 74 percent of Republicans said they would blame Biden and the Democrats in Congress if the government were to shut down. Just 5 percent said they would blame Republicans in Congress, and 16 percent said they would blame both equally. Five percent didn’t have an opinion or wouldn’t blame either.

The moderators just tried to move on, but Burgum interrupted to make sure he got a word in. He must have read my post at the beginning of the debate that he needs to get more words in edgewise!

We're hearing a lot of anti-union talk from candidates on stage tonight, but that's not a position that a majority of Americans take. As Cooper mentioned, a majority of Americans support the current UAW strikes. More than that, support for American unions are at highs not seen in decades. When Biden visited striking workers in Michigan this week, he was visiting a state that was the first since 1965 to repeal the anti-union right-to-work laws.

Several of the Republicans on stage touted their prioritization of border security should they win the presidency.

“What I’ll do on day one is sign an executive order to send the National Guard to partner with Customs and Border Patrol to make sure that we stop the flow of fentanyl over the border,” Christie said first. He expanded his answer to include his plans to fill the “6 million vacant jobs” in the country with legal immigrants.

“This border is going to be a day one issue for me as president,” DeSantis said, also noting that he’d administer the remain in Mexico policy, which requires migrants seeking asylum to remain in Mexico until their US immigration court date.

“We're going to declare a national emergency. Yes, we'll build the wall. We’ll do remain in Mexico,” DeSantis said.

Pence spoke about his role in negotiating the remain in Mexico policy of the Trump administration.

“I negotiated the remain in Mexico policy with the Mexican government. We used economic power to bring the Mexican government to the table. We build hundreds of miles of border wall and despite what's said here today, we reduced illegal immigration and asylum abuse by 90%. And as President of the United States, I can do it again,” he said. “I'm going to be ready on day one to get Congress to step up, secure the southern border of the United States.”

Haley cosigned on the Remain in Mexico Policy.

“Let's go back to Remain in Mexico policy,” she said. “Instead of catch and release. Let's go to catch and deport.”
Ramaswamy said that he was supportive of most of his opponents’ border positions, but that he’d go a step further: he’d end birthright citizenship for the kids of illegal immigrants.

“The Republicans on the stage are on the right side of this issue, militarize the southern border, stop funding sanctuary cities and end foreign aid to Mexico and Central America to end the incentives to come across,” Ramaswamy said.
