I believe they are holding the hard immigration cases as ransom for a much greater amnesty. If they can't get that, they prefer the status quo.
Democrats and Republicans oppose us. They try to tell us amnesty isn't really amnesty, as though we're too stupid to figure out what to call it when one is forgiven some or all of the mandated penalty for an illegal act. That is, of course, an amnesty, and it peeves me no end to hear fellow Republicans, our own team, blatantly lie about it rather than fess up to what they know is politically unpopular with their own constituents.
Rick Perry wants the border sealed and does not believe in amnesty.
He is the ONLY candidate running who will go after this.
