Look at how more and more minorities, especially when they become more independent and less reliant on government vote Republican based on their ideas. A lot of Hispanics are starting to agree with Republicans that we need a stronger border because illegal immigrants are hurting their communities (gangs, stealing their jobs, drugs, etc).
Where are you getting your data. I really do not know if more minorities are voting more Republican or not. Also I do not believe more minorities are reliant on government assistance. If anything more White people are more reliant but thats because they are still more white people in the US then minorities. The thing is the Republicans have had many times they could have reduce the government assistance programs and they have not. I believe this is more a talking point then anything else. Just like reducing the deficit is more a talking point when the Dems are in office.
