The thing is, those former Republicans are joined by countless others incuding many that were part of Trump's administration. They are just the latest to come foward in this election cycle.
Stephanie Grisham who served multiple roles in the Trump administration, mostly in communications, the most recent being chief of staff to first lady Melania Trump has endorsed VP Harris.
Olivia Troye who served as the Homeland Security and Counterterrorism adviser to former Vice President Mike Pence has endorsed VP Harris.
While not endorsing VP Harris, his own Vice President will not endorse him.
“The American people deserve to know that President Trump asked me to put him over my oath to the Constitution. … Anyone who puts himself over the Constitution should never be president of the United States.” --
Former Vice president Mike Pence
The only living former Republican president, George W. Bush, will not support Trump.

Some more recent endorsements from Republicans:
A dozen Republican White House lawyers who served in the administrations of then-Presidents Ronald Reagan, George H.W. Bush and George W. Bush are endorsing Vice President Kamala Harris in her race against GOP nominee former President Donald Trump.
"we urge all patriotic Republicans, former Republicans, conservative and center-right citizens, and independent voters to place love of country above party and ideology and join us in supporting Kamala Harris."
"Donald Trump’s own Vice President and multiple members of his Administration and White House Staff at the most senior levels – as well as former Republican nominees for President and Vice President – have already declined to endorse his reelection."
Those signing the letter pointed to what they called "the profound risks presented by his [Trump's] potential return to public office. Indeed, Trump’s own Attorney General and National Security Adviser have said unequivocally that Donald Trump is unfit for office, dangerous, and detached from reality."
The list includes Michael Luttig, the prominent right-of-center legal scholar and retired federal appeals court judge who previously served as assistant counsel to the president in the Reagan White House.
The list of signatories to the letter, besides Luttig, includes (in alphabetical order) John B. Bellinger III, Senior Associate Counsel to the President and Legal Adviser to the NSC under George W. Bush, Phillip D. Brady, Deputy Counsel to the President under Reagan, Benedict S. Cohen, Associate Counsel to the President under Reagan, Peter D. Keisler, Associate Counsel to the President under Reagan, and Robert M. Kruger, Associate Counsel to the President under Reagan.
Also included are John M. Mitnick, Associate Counsel to the President and Deputy Counsel, White House Homeland Security Council under George W. Bush, Alan Charles Raul, Associate Counsel to the President under Reagan and General Counsel, OMB under Reagan and George H.W. Bush, Nicholas Rostow, Special Assistant to the President for National Security Affairs and Legal Adviser to the NSC under Reagan and George H.W. Bush, Peter J. Rusthoven, Associate Counsel to the President under Reagan, David B. Waller, Senior Associate Counsel to the President under Reagan, and Wendell L. Willkie II, Associate Counsel to the President under Reagan.
