As Biden touts his support for Ukraine in its war against Russia -- calling it out as one of his defining successes of the past year -- he is speaking from a position of relative strength: Americans generally feel better about Biden's Ukraine policies than about his domestic ones. For example, a recent ABC News/Washington Post poll found that his approval rating on the Russia-Ukraine conflict (38%) was higher than on the economy (37%) or the immigration situation on the U.S.-Mexico border (28%).

In addition, according to Gallup polling, a plurality of Americans (39%) think the U.S. is doing the right amount to help Ukraine, while 30% think the U.S. is not doing enough and only 28% think it is doing too much. However, as my colleague Cooper Burton wrote last month, support for aiding Ukraine has cooled a bit since the war started in February 2022, thanks in large part to decreased enthusiasm among Republicans.

One of the night's more contentious moments came when discussing the debt ceiling and the White House's disagreements with Republicans on government borrowing and spending.

"Some of my Republican friends want to take the economy hostage unless I agree to their economic plans," Biden argued. "All of you at home should know what those plans are. Instead of making the wealthy pay their fair share, some Republicans want Medicare and Social Security to sunset."

The remark was met with resounding boos, and GOP Rep. Marjorie Taylor Greene could be seen calling out "liar."

Speaker McCarthy has also publicly said potential cuts to Medicare and Social Security are "off the table."

Biden continued on to say that he didn't think it was a majority of Republicans or even a significant number, and that he was "politely not naming them."

Based on the booing, he said, "So folks, we all apparently agree, Social Security and Medicare off the books now, right?" he said, which was followed by applause. "All right, we got unanimity."

"Let's stand up for seniors," he added. "If anyone tries to cut Medicare, I will stop them, I will veto it."

Biden is making the argument that his immigration policies have improved the situation at the southern border. However, Americans may not buy it. Poll after poll suggests that Biden's approval ratings are weakest on immigration. For example, ABC News/Washington Post's latest poll found that his approval/disapproval rating on the immigration situation at the border is just 28% approval compared to 59% disapproval. And a January poll from Quinnipiac University had even worse numbers for him: Only 18% approved of his handling of the situation on the Mexican border, while 68% disapproved. That was the lowest that number has ever been in Quinnipiac's polling.

As Biden turned to discuss policing and public safety in his address, he took a moment to welcome the parents of Tyre Nichols, the 29-year-old Black man who died last month after being assaulted by police in Memphis, Tennessee.

His mother, RowVaughn Wells, and his stepfather, Rodney Wells, received a standing ovation from those gathered in the chamber.

"What happened to Tyre in Memphis happens too often. We have to do better," Biden said. "Give law enforcement the training they need, hold them to higher standards and help them succeed in keeping everyone safe."

The president called for more resources to reduce violent crime, more community intervention programs and more investments in housing, education and job training.

"Let’s commit ourselves to make the words of Tyre’s mother come true, something good must come from this," he said.

While lawmakers in both parties said after Nichols died that they would like to pursue a compromise on policing reform, previous such efforts have failed in Congress.

Biden is expected to announce within months that he is seeking reelection in 2024, a source previously told ABC News.

As he prepares his next move, FiveThirtyEight’s polling average shows that his approval numbers are slowly ticking up from where they were last fall. On Feb. 7, Biden hit a 43% approval rating in FiveThirtyEight’s average -- an increase of 2 points since Nov. 8, the day of the 2022 midterm elections.

This might not seem like a huge increase in the grand scheme of things, but in the current age of strong partisan polarization, any upward trajectory is likely encouraging for Biden ahead of him officially announcing another run.

On the other hand, polling does show that Biden enjoys relatively mild support for another campaign from inside his own party, with only 58% of Democratic primary or caucus voters saying they want Biden to be their nominee in 2024, according to an Emerson College poll released in late January, while 42% said it should be someone else.

That 58% is a 6-point drop from when Emerson asked Democrats the same question in June. But Biden has stronger support among some key demographic groups: According to the poll, 75% of Black Democratic voters and 72% of Hispanic Democratic voters want Biden to be their standard-bearer. White Democrats are more divided, with 51% saying someone besides Biden should be the nominee.

A new ABC News/Washington Post poll found similar concerns among Democrats about Biden being renominated in 2024.
