"A better controlled border with less fentanyl,"
Synthetic Opioids (fentanyl) overdose deaths in 2021 were 71,238 compared to 57,834 in 2020, which that's a 23.2% increase. Now compared fentanyl overdose deaths in 2020 to 2019. There were 57,834 Fentanyl overdose deaths in 2020, compared to 36,359 in 2019, which was a 37.1% increase.
So yes Biden had to deal with the fentanyl overdose deaths but the problem started under Trump.

"Chinese spying,"
This one is easy to debunk. The three aerial objects what we first thought were Chinese spy balloons were actually discovered that they weren't even spy balloons from China, they are likely to be discovered as private company balloons. But during the Trump era, there were three Chinese spy balloons that were hovering around the US and the Trump administration weren't even aware of it.
