An expert believes the Republican voter base will turn on both Donald Trump and the GOP in the midterms next year.

Close calls in recent elections and a handful of key victories for Democrats across the country in mayoral and governor races has put the GOP on alert, though it may already be too late. Republican strategist Barrett Marson says the economic hardships under the Trump administration will be a key decider in voting next year, which could see voters "turn their ire" on the president.

While Trump has constantly claimed the economy is improving and that he is plugging away at the deficit left by the Biden administration, people are still feeling the crunch of tariff policies. Healthcare remains a thorn in the side of the administration too, an issue which led to the longest government shutdown in history.

Strategist Marson believes the end of the road is in sight for the GOP if they do not adapt to clear warning signs seen in elections and voter turnout of the last few months. He told Politico, "Voters aren’t going to go, ‘I voted for Trump to better the economy, but Biden just hamstrung [him] too much.'"

"Voters are going to very quickly forget about Joe Biden and just as quickly turn their ire to Trump unless things get better." CJ Warnke, a spokesperson for the Democratic super PAC House Majority PAC has since suggested Democrat candidates will hone in on the shortcomings and broken promises of the administration.

Warnke said, "House Republicans should 100 percent expect to see ads next year calling them out for their broken promise to lower prices and for supporting Trump’s tariffs."

Voting in Tennessee may have seen Republican candidate Matt Van Epps win over Democrat candidate Aftyn Behn, but the narrower margin than expected in other races should have the GOP worried, a strategist said.

A strategist speaking on Republican Andy Ogles' campaign suggested that the financial gap between how much cash the former Maury County mayor had raised and how much the Democrat candidate had raised is now a bridge too far.

An unnamed strategist said, "I mean, he’s raising like no money. You can’t just lie around and do nothing. That’s how you lose any race — primary or general." Other GOP strategists have a "very serious concern" over how Ogles is running his campaign for re-election.

Rep. Richard Hudson, chair of the National Republican Congressional Committee, backed the anonymous strategist and said the strength of a campaign comes from its financial backing.

He said, "But obviously, the more money you have in your campaign account, the stronger you are, the more opportunity you have to communicate with the voters. You might have raised a red flag for me."
