The Washington Examiner reports that numerous Republicans are targeting U.S. Sen. Kyrsten Sinema's (I-AZ) seat. 

Sinema is up for reelection in 2024, and experts have suggested that her seat may be vulnerable.

Democrat to Independent

This comes after Sinema recently left the Democratic Party and registered as an independent. Sinema made that decision just after the Democrats, in the 2022 midterm election, increased their majority in the U.S. Senate from 50-50 to 51-49.

Sinema's departure from the Democratic Party was not the biggest surprise as, in recent years, she had frequently stood in the way of some of the Democrats' top legislative desires.

In an op-ed explaining her decision to leave the Democratic Party, Sinema wrote, "when politicians are more focused on denying the opposition party a victory than they are on improving Americans’ lives, the people who lose are everyday Americans."

"That’s why I have joined the growing numbers of Arizonans who reject party politics by declaring my independence from the broken partisan system in Washington," she concluded. "I registered as an Arizona independent."

The reason that experts believe that Sinema's seat may be vulnerable is that, like always, she probably isn't going to get much support from Arizona Republicans, and, now that she has left the Democratic Party, she might not get much support from Arizona Democrats either.

The field is crowding

According to the Examiner, several Republicans are now lining up for Sinema's vulnerable senate seat - including some big-name Republicans.

Those big-name Republicans are Kari Lake and Blake Masters. Both were endorsed in the midterms by former President Donald Trump but suffered defeat in their individual races - Lake for Arizona's governorship and Masters for one of Arizona's U.S. Senate seats.

The Examiner reports, however, that Lake and Masters are just two of many Republicans eyeing Sinema's senate seat.

Per the outlet:

Among the possible GOP contenders are Lake, Masters, U.S. Reps. Andy Biggs (R-AZ) and Juan Ciscomani (R-AZ), Pinal County Sheriff Mark Lamb, Karrin Taylor Robson, and Arizona GOP Chairwoman Kelli Ward.

A look ahead

Experts are predicting that Democrats are going to have a difficult time holding onto their U.S. Senate majority in 2024.

The reason for this is that 22 out of the 34 U.S. Senate seats that are up for reelection in 2024 belong to Democrats, and several of these Democrat-held senate seats are in swing states or areas in which Republicans are slightly favored.

Sinema's senate seat is on this list.
