"I do not support any proposed gun control which would limit the right to gun ownership," Sen. Rand Paul said in a campaign ad.
As far as punishment for criminals goes, American voters generally support the death penalty in certain situations. A Gallup poll found that Republicans are more likely than Democrats to support it.
One of the most controversial aspects of the death penalty is how it's carried out.
Violence against women has become another campaign issue for some candidates. Sexual assault on school campuses has increasingly become a national issue. And sexual assault in the military is another topic some candidates are talking about.
While crime itself will probably always be a talking point during elections, debates are more likely to highlight specific issues such as the death penalty or gun control.
