As of my last update in October 2023, I can provide information on general trends in past elections in Texas and Michigan. In the context of presidential elections and other political races, margins of victory can vary widely.
Historically, Texas has leaned toward Republican candidates, and margins of victory for GOP candidates often exceed 4%. For instance, in the 2020 presidential election, Donald Trump won Texas by a margin of approximately 5.6% over Joe Biden.
Michigan, on the other hand, has leaned more Democratic in recent elections. In the 2020 presidential election, Joe Biden won Michigan by a narrower margin of about 2.8%. However, margins can also depend on individual races (for governor, senators, etc.) and voter turnout.
For the most recent and specific margins of victory in Texas and Michigan for various candidates, particularly for elections after 2020, I would recommend checking official state election websites or reputable news sources for the latest results.
