Roll Call believes that former President Donald Trump is likely to choose one of five individuals to be his 2024 running mate. 

The five individuals include South Dakota Gov. Kristi Noem (R), Arizona Republican Kari Lake, U.S. Sen. Tim Scott (R-SC), former South Carolina Gov. Nikki Haley (R), and U.S. Rep. Elise Stefanik (R-NY).

The reader will likely recognize that a big name is missing from this list, namely, Florida Gov. Ron DeSantis (R). DeSantis is currently Trump's top rival in the 2024 Republican presidential primary, although he trails Trump significantly and has been trending in the wrong direction.

Previously, many Republicans were hoping for a blockbuster Trump-DeSantis ticket. But, apparently, Roll Call believes that this particular bridge has already been burned.

Why these five?

Regarding Noem, Roll Call points to Trump's recent visit to South Dakota, where he received Noem's endorsement. Roll Call writes, "The bold Trump-Noem 2024 sign on the video board behind the event’s stage looked awfully intentional." The outlet, however, fails to indicate whether these are the only two reasons why Noem has made the list.

The fact that Lake is on the list, however, is no surprise to anyone. Trump-Lake has been one of the most talked about 2024 tickets, as it is clear that Lake is one of Trump's top allies. Recently, however, there have been reports that Lake might make a run at the U.S. Senate.

Roll Call's decision to include Scott on the list is a bit more unclear. The outlet seems to suggest that it would be for two reasons: Scott's race and his religion.

Roll Call is clearer with regard to Haley, writing, "Haley would bring multiple layers of diversity to the ticket (potentially setting up a historic vice presidential debate between two Indian American women) and foreign policy experience."

Finally, the best that Roll Call could come up with for putting Stefanik on the list is that she is "a prominent Trump apologist."

Why the VP talk now?

The simple answer is that Trump is currently dominating the Republican field by such a wide margin that it has become a foregone conclusion that he will be the Republican Party's 2024 presidential nominee.

Real Clear Politics, for example, currently has Trump up 44.4 percentage points over his next closest rival, which is DeSantis. On individual polls, Trump's lead is even bigger. And, perhaps more importantly, Trump's numbers have only been getting stronger.

Trump, in fact, is dominating the Republican field so much that President Joe Biden, according to reports, has already decided to start campaigning against Trump, on the premise that Trump will be who he faces off against in the 2024 general election.

So, Trump's sizable lead is the reason why many commentators are already looking forward to the Biden-Trump general election matchup and to potential running mates for Trump.

Thus far, Trump has given no indication as to whom he will choose.
