I asked Grok:

How many republican senators are in the US senate at this time who are capable of casting a vote?

Answer:

52 Republican senators are currently capable of casting a vote in the US Senate.

The 119th Congress (2025–2026) has 52 seated Republicans, 45 Democrats, 2 Independents (who caucus with Democrats), and 1 vacancy, for a total of 99 voting members. ballotpedia.org

• There are no widely reported cases of Republican senators currently incapacitated or unable to vote as of July 12, 2026. All seated senators are presumed able to participate unless a specific medical or other issue is publicly noted (none appear in recent updates).

I then asked if Grok was counting Mitch McConnell:

51 Republican senators are currently capable of casting a vote.

npr.org

• Sen. Mitch McConnell (R-KY) has been hospitalized since June 14, 2026 (nearly four weeks as of July 12), and remains absent with limited public details on his condition or return timeline. npr.org
• This leaves 51 active/voting Republicans out of the 52 seated ones (plus 45 Democrats, 2 Independents caucusing with them, and 1 vacancy).

I then asked if Grok was counting Lindsey Graham:

No — Lindsey Graham is not being counted among those capable of casting a vote. He died suddenly on July 11, 2026 (yesterday) at age 71 after a brief illness (reported as cardiac arrest). His seat is now vacant, and a temporary replacement will be appointed by South Carolina Gov. Henry McMaster, followed by a special primary and election process.

50 Republican senators currently capable of casting a vote.

• This accounts for:
  • Sen. Mitch McConnell (R-KY) still hospitalized and absent since mid-June.
  • Sen. Lindsey Graham (R-SC) deceased.
• Total seated Republicans: 50 (out of the prior 52).

Sen. Markwayne Mullin (R-OK) resigned in March 2026 after being confirmed as Secretary of Homeland Security in the Trump administration. This created the vacancy that showed up in the 1-vacancy count before Graham’s death.

The Republican majority in the US Senate is gone. Thune, Tillis, Murkowski and Collins are effectively Democrat votes. That leave 46 Republican senators.
