A friend from Minneapolis explained that the Somalis vote as a group(their tribe). Whoever the tribal leader says to cast your vote for gets 100% support for that politician.
This is why they can get so much leverage.
They turn out and vote as a block.
So, that politician is indebted to them especially in close races or primaries.
Lots of “groups” do that. We have a Pakistani in our boat club, his mosque votes as a group. Remember last election the Pakistanis were threatening to all vote for Trump because they were being mistreated by Biden or something. They typically vote for the Democrat but wanted to flex their muscles. These people don’t really assimilate, no more melting pot.
