100%. Folks that voted for Biden probably will again. Idiots that voted for Trump probably will again. Anecdotally I doubt any conservatives are going to switch over and vote Biden due to his accomplishments. If you know any Trumpanzees or conservatives in general their talking points are inflation of goods prices and the price of gas. Like it or not things are quite a bit more expensive right now, and it happened under Biden. 401K's are not doing as well either generally right now. If Biden could tout his accomplishments and get inflation under control it would make a lot stronger case with swing voters.
His position on Israel certainly isn't helping his chances of re-election, nor will it swing any conservative votes his way regardless. In my view he can only hurt himself, not improve his position with policy as he is generally unpopular.
It's not quite this simple though. Trump won in 2016 because a small number of votes in the Rust Belt flipped (and some Dems stayed home instead of voting). In 2020, many of those same Rust Belt voters felt comfortable enough with Biden to carry us by narrow margins. It's not like those margins of victory in the Rust Belt reverted back to comfortable pre-2016 norms. Elsewhere although it didn't affect any states that I know of, minority voters actually shifted
towards Trump in 2020, AFTER all the menace he had wreaked in his first term! It took Herculean efforts to flip Georgia.
So yes the vast majority of the electorate isn't changing its minds, but a sliver of swing voters (as you mentioned) in a handful of states have outsized influence on the outcome.
Generally speaking, Americans do not care about foreign policy unless we have "boots on the ground." Most probably couldn't point to Israel on a map if you asked them, and they don't give two fucks about the Middle East.
Having said that, I disagree with the blanket statement that Americans overwhelmingly want a more robust pro-Israel policy. That might have been the case in the immediate aftermath of the Hamas attacks, but public sentiment has definitely shifted in recent days. Also, give the administration some credit where it's due. Diplomatically we're leaning tirelessly on Israel to not ignore humanitarian needs; unfortunately their leadership generally refuses the message. You may think a 4 hour daily pause isn't much, but that is a direct result of Biden applying pressure on Israel.
Inflation is under control.
This is not the right way to look at things, because inflation is clearly a top reason why the electorate is judging Bidenomics very harshly right now. Although economists will tell you inflation is under control, the average Joe is not an economist. What do I mean? There were some "transitory" spikes such eggs a year ago, fuel, and Tesla autos. Those prices are now back to where they were before the supply chain melted down, so those price spikes were not permanent.
BUT in many goods and services, prices went up a lot and will stay there for good. Your $11 Big Mac combo isn't going back down to $9 because inflation has ebbed. Americans don't much care that the interest rate policy has tamed inflation; they're just mad about the cost of things in general. And because Biden is POTUS, he gets the lion's share of the blame.
And notice that while people harshly blame POTUS for price levels, he gets zero credit for $3/gal gas as 50M people get ready to hit the road for Thanksgiving gatherings.
