The regime haven't got the numbers to target all of the blue states (or more specifically the major cities that those states revolve around) at once. So they've hit them one or two at a time. Los Angeles. Portland & Chicago. And now the Twin Cities and Maine.
The Minnesota Governor was Kamala Harris's running mate in the 2024 Presidential Election so it's personal for the regime.
During covid some dodgy nonprofits were allocated funds for providing meals to vulnerable children. It was a fraud, it got investigated, they got prosecuted. There was no evidence to suggest that Minnesota officials were in any way corrupt. Lots of countries had these sort of issues during the pandemic, funds were sent out without proper checks being made, think PPE in the UK.
The ringleader of the scam was a white woman, but many of those also convicted were Somali-American (note, if they are "Somali-American" then they are US citizens who were either born or naturalised into the US, not "illegal aliens").
After two National Guardsmen were shot in Washington DC last year, Trump used it as an excuse to not only target Afghanis but also Somalis. A far-right Youtuber posted a video on Boxing Day last year alleging widespread fraud in Minnesota daycare centres. There was no evidence to suggest that many of his claims were true.
This riles up the MAGA base into a hate campaign against the state and its Governor - who withdrew his candidacy for reelection because his family was being targetted.
And now the Federal Government has flooded the streets with thousands and thousands of thugs, giving them carte blanche to attack the population.
