In fact they already are taking over the government.
State Senator Gil Cedillo (mexican) authored the "California DREAM Act" which gives kids of illegal mexicans preference in getting student loan/grant money, and precious slots for admission to Univ Calif. it is claimed they get preference OVER children of taxpaying citizens. http://www.csac.ca.gov/dream_act.asp
The republican governor Terminator vetoed it, so the democrats simply waited until a democrat took the governorship then pushed it into law. gov jerry moonbeam brown signed it into law.
When I went to get a replacement SS card the mexican girl working the counter immediately granted a ss card to a mexican illegal there in the lobbywhile I was. I was going to complain to the supervisor, till I saw he was mexican too. True story.
I'm going to call bullshit on your story.
