The meme is not only did they not turn ‘weak’ red states like Texas or Ohio or Iowa or Florida into swing states, but 3 safe blue states instead ended up becoming Swing States and Arizona is now a red state.
Arizona has been pretty solidly red for Presidential elections for a while. It may be considered a swing state because of other aspects, but it’s been almost entirely red for Presidential elections since at least the 70s.
Virginia and to a lesser extent NJ you could argue were redder then they really are due to factors like Youngkin, an extremely left leaning third party spread(Virginia the worst in the nation for the democrats), and Trump’s local popularity in NJ.
But if you make that argument New Mexico and Minnesota and New Hampshire are the opposite, local factors and third parties were against Trump and he still did really well. If you want my honest 2024 swing state map prediction swap out Virginia for New Mexico
