Will any big name Republicans publicly admit to voting for Hillary?

[Lyin' Steve]

McConnell is back again today saying Trump "doesn't know a lot about the issues."  Seems patience is wearing thin across the board already.  How will they hold up until November?
Which of the following will come out and admit they're voting for Hillary, for whatever reason?

• Ben Sasse
• Lindsey Graham
• John Kasich
• Marco Rubio, after he officially surrenders his political career
• Ted Cruz??!
• Mitch McConnell
• Paul Ryan
• John McCain
• Susan Collins
• Mark Kirk
• Bill Kristol
• Mitt Romney

etc. add your own

Not until they write their memoirs decades from now.

Bill Kristol.  He'll call it a protest vote and write French in as her running mate.

None of those currently in office will admit to voting for Clinton.  However, Ray LaHood, Chris Shays, and Christine Todd Whitman have all said that they're #NeverTrump, and any of them might end up admitting to voting for Clinton.  Do they count as "big name"?

In all likelihood, the biggest name Republican who will admit to voting for Clinton will be Colin Powell.

The biggest Republican names who will vote for Hillary but never admit it are:

George H.W. Bush
George W. Bush
John McCain
Mitt Romney

[Beefalow and the Consumer]

None, unless they plan on switching parties.  Which is not entirely out of the question.

[Mr. Illini]

Susan Collins has floated it already.

It will depend on what course Trump takes. If he goes full-speed-ahead at November making comments like he has recently, good candidates are Mark Kirk and Rob Portman (esp. if he starts slipping in his race).

Does Laura Bush count? She already hinted at it
