Appearing on ABC’s “This Week” on Sunday, Meghan McCain of “The View” told host George Stephanopoulos that President Trump’s recent tariff decisions, as well as his seemingly shifting stance on the Second Amendment, will drive away his base:

STEPHANOPOULOS: With an action like this on trade, he alienates the leaders in Congress, the Republican leaders in Congress, who have been backing him when he needed it.

MCCAIN: Yeah, and this is coming off his discussion about the NRA and his seeming hedge on the Second Amendment earlier this week. You want to talk about loyalists leaving? Start screwing with the Second Amendment and the cost of what your beer will cost with your aluminum can — I'm telling you, that will be something that will finally make his base move.

On Thursday, President Trump announced that he planned to impose new tariffs on steel (25%) and aluminum (10%).

Some business leaders and experts are deeply troubled by the president’s actions. CNBC quoted chief financial economist at Jefferies, Ward McCarthy, who said, “Tariffs would probably have the unfortunate effect of both slowing growth and accelerating inflation, and that's not a good thing.” McCarthy added that “this is the worst possible time to be doing that.”

Republican lawmakers have also been critical of the president’s tariff ideas. Appearing on Fox News’ “Special Report” on Thursday, Sen. Ben Sasse (R-NE) stated:

Trade is great for America; trade is great for American families; and no trade war has ever worked. We don’t want to make America 1930 again, and the forgotten men and women of America don’t want to be drafted into a trade war. It doesn’t work. Trade creates jobs — all the data shows that — and trade lowers prices for American families. Trade wars do the opposite.

Some Democratic leaders, however, are praising Trump. On Thursday, Sen. Bob Casey (D-PA) tweeted:

Trump has long been a critic of “globalization,” having frequently argued for protectionist policies during his 2016 presidential campaign.
