Missouri is playing host to one of the year’s most competitive Senate races, and Attorney General Josh Hawley is supposed to be among the top Republican recruits. But some Republicans from the Show-Me State are starting to raise questions about his campaign’s performance so far.

Republicans are still optimistic about their chances of defeating Democratic Sen. Claire McCaskill in a state President Donald Trump won by 20 points. And they’re generally still confident in Hawley, who garnered more votes than Trump in his run for attorney general in 2016.

“He won his first statewide race handily,” Missouri Sen. GOP Roy Blunt said Monday evening. “I think he’s a good candidate. I’m not concerned, but it’s a tough state and you have to work hard.”

Missouri is one of the few states where Republicans had appeared to avoid a costly and divisive primary. But Politico reported Friday that GOP Rep. Ann Wagner had been approached about reconsidering her decision not to run for Senate, raising concerns about whether Republicans were losing faith in Hawley.

In recent days, some Republicans have been questioning Hawley’s fundraising and lack of campaign activity in the four months since he officially launched his campaign.
