The commentary on "Morning Joe" comes as the RealClearPolitics average of polls shows the race between Democrat Conor Lamb and Republican Rick Saccone as a toss-up.

“Listen, I think this [imposing tariffs] is all about Pennsylvania 18," Scarborough said. "He’s going to wait till Pennsylvania 18 is over and then he’s going to pull back on this."

"They’ve got a race in the suburbs, in Pittsburgh. They let that play out next Tuesday, he pulls back, decides not to do it," he continued.

The president has faced widespread criticism, especially from members of his own party, on the decision to impose a 25 percent tariff on steel and 10 percent tariff on aluminum over fears it could hurt the economy while sparking a trade war.

Some Democrats and the AFL-CIO, the largest union federation in the country, have endorsed the decision.

GOP strategists and other nonpartisan political pundits believe the president, in looking ahead to his 2020 reelection bid, is using the tariffs to focus on holding onto key "blue wall" states that had voted Democratic for years before the president surprisingly won them in 2016.

“Clearly he’s targeting Michigan, Wisconsin, Ohio and Pennsylvania. Those were, all four, key battleground states for him in the last election and the states he would have to win if he’s going to win reelection,” Saul Anuzis, a political strategist and former chairman of the Michigan Republican Party, told The Hill.

“It’s a very calculated, direct move with regards to the constituency he needs,” he added. “Campaigns are no longer limited to months before the election but literally start the day after someone gets elected.”
