I'm interested why biden fans think he's going to win these swing states he's polling horribly in, what has he done to give you indication that polling is signicantly inaccurate? The trump is bad rhetoric doesn’t seem to be moving much in the party right now, he's broken multiple promises and currently funding 2 wars during a downturn
For multiple reasons.
-Many voters who don't pay attention to the day by day have not realized that Trump is going to be the Republican nominee. The Biden campaign team has internal data on this and it's been mentioned several times by pundits separately. Once voters realize he is the nominee, I believe the narrative will completely shift.
-Political news cycles change every 4 to 6 months. Trump getting convicted on the January 6th federal case will be the main news story for months, and will make him un-electable in eyes of many independent voters and anti-Trump Republican voters. Any other conviction will just add to it. Especially in swing states. They will vote for Biden. That's thousands of votes. They will realize he's a convicted felon running for President to stay out of jail.
-The election will not be a referendum on Biden unless the economy crashes. It will be a referendum on Trump.
-Inflation is cooling, but Biden has not been getting credit for it as reflected in the polling. It's possible there is a delayed reaction where Biden starts getting credit in the summer as inflation continues to go down.
-With some exceptions, the election is really won in the last 120 days and most voter memories are short. (But they won't forget Trump being convicted) The issue of today may not be the issue in the fall.
History is also on Biden's side. Trump has lost election after election since he was President.
-Lost the House in 2018. (Expected for any President, to be fair)
-Lost the Senate and White House in 2020.
-Republicans under performed in 2022 midterms when everyone was screaming Red Wave. Roe vs Wade being overturned caused a big change in voting, but also voters viewed Republicans as extremist garbage. Republicans actually blamed Trump for the poor performance because he had MAGA supporters win primaries and lose in the general election, while Republicans felt more moderate candidates could have won in the general election. Dems pretty much had a clean sweep of all the swing states. They split Wisconsin. (I'm still upset about that because the right candidate would have defeated Ron Johnson)
-Dems won in 2023 elections.
The MAGA Republican voter base is law of subtraction, not a law of addition. It's a shrinking mess that causes Trump to have a ceiling of how much vote share he can get in the general election voter base because Trump and the MAGA movement turns off so many people. Biden on the other hand can have that big tent of voters needed to win in a general election.
More history:
-The media ran stories saying polling suggested Reagan shouldn't run for re-election. He won re-election in a landslide.
-The media had stories about people saying Clinton shouldn't run for re-election after the GOP wiped out Dems in the 94 midterm elections. Clinton won re-election.
-Bush won re-election and the popular vote while dealing with two unpopular wars and protests.
-The media even had stories about Obama saying he would lose to Romney. Romney also pulled ahead on polling before the election. Obama won re-election.
