The conservative movement has existential worries about the increase in spending, particularly as vaccines fuel a better economy and inflationary fears grip consumers — and send the stock market diving, as happened Monday.

They’re wary of going on the record supporting a package that includes such a steep price tag, particularly after Congress already passed a $1.9 trillion coronavirus package this year.

They’re also terrified of being held responsible for killing a bipartisan deal for something everyone loves: roads, bridges and photogenic local pork.

All this comes as they try to message against “reconciliation” and “inflation” — two terms not well understood by everyday Americans — and search for ways to simplify their attacks.
