Shopping at places that are at least 'friendly' to the GOP increases the chances (but of course does not guarantee) that the stakeholders are inclined to be law-abiding and employ 'legals.'
If we don't buy SOMEPLACE on Monday, we help endorse the illegals' cause.
Buying on Sunday or Tuesday instead of Monday won't have any effect on businesses in this country. It's the same basic concept as the silly gasoline station boycotts. "OK, nobody buy gasoline next Wendesday." So, everybody fills up on Tuesday instead. Big deal.
Money talks..money is power. (We got the power!) Monday is the time for all good patiots to come to the aid of their country..
Talk it up, people.
