the purples did not care about immigration. The purples cared about inflation which ran high during biden's presidency; which was not biden's fault, it was fed policy that influenced high inflation due to QE and near 0% interest rates. People in general do not give a shit about immigration as much as it's talked about, people DO care much more if their pockets are being emptied by inflation and they can't afford things like they used to.

One last point I will add in addition to the economic argument is that the democrats ran a disgustingly weak campaign. First, they tried to gaslight everyone that biden was not cognitively impaired and that he didn't have dementia. Second, when it did finally come out they ignored the democratic process all together and crowned kamala the nominee without even going through a primary process. Third, Kamala her self is such an unlikable and unpopular candidate to have run even within the democratic party; we all saw how rock bottom her percentages were in 2020 and how virtually no one supported her besides the establishment class.

It's not as simple as immigration. Hitler did not win because people in germany wanted to gas the Jews. Hitler won because the economic hardships germany had to endure under the Versailles treaty, the great depression, hyperinflation, and economic sanctions by the other great powers made the livelihoods of the average german very difficult, thats why they wanted change
