Trump’s campaign has pointed out that most of his rallies in unusual states have been linked to fundraising events scheduled nearby, to maximize the value of his travel. But this tack has bewildered some political professionals, who worry Trump is squandering the campaign’s most valuable resource: the candidate’s time.

“What he’s not realizing is, there’s a cost to everything you do. Every additional rally gives you a chance to create a controversy or make a mistake,” said Matt Mackowiak, a Republican strategist based in Austin. “I can probably think of eight or 10 things that would be a better use of his time. Debate prep, policy briefings, meetings with staff. Literally, taking a nap would be a better use of his time.”

Trump’s allies have stressed that the candidate is able to amplify his campaign message from his rallies, wherever they may be. Meanwhile, the crowds that a state like Mississippi can draw for Trump project an aura of excitement and momentum around his campaign.

“Having a backdrop in a friendly state is sometimes a good thing as a candidate,” said former Rep. Jack Kingston, a senior adviser to Trump. “Whether he’s in Texas or Virginia, he’s still talking to the entire nation.”
