2019 has been quite good for Republicans so far. First they consolidated the Wisconsin Supreme Court; then they won an election where their last guy was convicted of fraud; now they win a super-majority in the Louisiana State Senate and possibly House. These are the main elections where "The Squad" has been the face of the Democrats.
Winning by less than a point in a 20% turnout race with no parties on the ballot, squeaking by in a Trump +13 House seat, and winning supermajorities by flipping seats that went to Trump by 30 or more points.
If you really think any of these are because of “The Squad”, you need to stop talking about elections.
