They always say this.
@Weird Tolkienish Figure Doesn't mean it isn't true.
Here are some actual truisms for you.
1: NO Ilegal alien is going to vote Republican
2: Illegal aliens tend to have a LOT of children.
3: NONE of those children are going to vote Republican.
4: The number of big city blacks that will vote Republican is negligible,and falling.
5: Blacks tend to have a LOT of children.
6: None of those black children are going to grow up and vote Republican.
7: White people are a minority in many areas of the country,and there are fewer every year due to deaths and the tendency of white people to only have 1 or 2 children.
8: The DNC/Left has an absolute LOCK on the media and how they report news and influence chowderheads.
IOW,we either win it this time and start making changes in how elections are ran and immigration laws,or America is over.
