Or used to stand for, for that matter.
What
Republicans have stood for from day one is quite clear. Life, liberty and property for all people. No exceptions. For legal immigration. For state sovereignty. Against profligate government spending.
In other words: against what the Democrats stood for in 1860...and in some cases stand for today.
A word of advice for today's Republicans: all it took to for the downfall of a party that dominated national politics was the abandonment of a single provision in the above list. The sooner you declare that foolish spending was wrong the sooner people will consider trusting you again.
