Well, that is not what 2008 and 2012 showed when it came to voting.
That just means the majority haven't found a path to success (or haven't worked hard enough on it) and support 'rats for the "free stuff".
Pandering to them is not going to change their support unless those doing the pandering offer more than the 'rats.
If they're legal, they don't fear deportation and most I've talked to don't support open borders, either.
If that is true, which I doubt, then it is all the more reason not to 'regularize' these Mestizos.
