Even as Donald Trump and Republican Party bosses diligently work Capitol Hill in hopes of bringing the party together after a fractious presidential primary, convention planners could still be looking at a block of empty seats for the July convention.

A growing roster of senior GOP figures – from governors to senators to, most notably, nearly every living GOP presidential nominee – is vowing to skip the convention in Cleveland, despite the candidate starting to win over the rank-and-file.

In an unconventional election season where Trump has capitalized on an anti-establishment fervor, the case can be made that Trump does not need the blessing of party elders, or their attendance.

“Trump is a master entertainer and more than likely going to put together a convention program that attempts to highlight his strengths and sideline some of the major absences,” Republican strategist Ron Bonjean told FoxNews.com.

Still, since wrapping up the nomination, Trump and his surrogates have been regularly meeting with Hill Republicans, showing at least an effort to pursue party unity – a message that high-profile absences in Cleveland could undercut.
