Here are two fantastic articles both of which offer plenty of ammunition (ahem) against those red-state Trump gun lovers who talk about violence and crime as if it is a Democrat problem.

Key takeaways:
The murder rate in the 25 states that voted for Donald Trump has exceeded the murder rate in the 25 states that voted for Joe Biden in every year from 2000 to 2020.
Over this 21-year span, this Red State murder gap has steadily widened from a low of 9% more per capita red state murders in 2003 and 2004 to 44% more per capita red state murders in 2019, before settling back to 43% in 2020.
Altogether, the per capita Red State murder rate was 23% higher than the Blue State murder rate when all 21 years were combined.
If Blue State murder rates were as high as Red State murder rates, Biden-voting states would have suffered over 45,000 more murders between 2000 and 2020.
Even when murders in the largest cities in red states are removed, overall murder rates in Trump-voting states were 12% higher than Biden-voting states across this 21-year period and were higher in 18 of the 21 years observed.
