If they wanted someone who wasn’t weak on illegal immigration, why were they supporting Scott Walker? He specifically supported amnesty and citizenship for illegals. Then he briefly didn’t. Then he did again.
He had a record against it. Not a whole lot, but more than most running. Then he came out with including legal immigration curbs.
Couple that with the small government reforms and states’ rights issues. Throw in Castle Doctrine, CCW, defunding PP, etc. and you have a good cocktail.
Walker’s PAC still has the majority of the money they raised and it’s not chump change. Walker also set up a grassroots network that could easily switch to another candidate that matches similar supporters, so who knows what will happen?
