It's no secret that the Republican Party is split right now; while millions and millions of Republicans voted for the party's presumptive presidential nominee, Donald Trump, the party leadership is still wary of hitching its wagon to him, for fear of the consequences in 2016 and beyond.

Some of them struggled to endorse Trump, coming up with halfhearted praise and a collective "meh." And now a whole group of party elites won't attend this month's Republican National Convention in Cleveland, thinking that it would devolve into some kind of Trump-infused circus.

Of course, that's not their stated reason for skipping out. No, they have a variety of excuses: They're too busy running their own campaigns, they'd rather watch on television, or they have previous engagements scheduled (like Arizona Sen. Jeff Flake, who apparently has to mow his lawn for the entire four-day political extravaganza).

Some didn't even bother with an excuse, like Nevada Gov. Brian Sandoval. Neither of the living Republican former presidents — George W. Bush, nor his father, George H.W. Bush — will attend. And Jeb Bush, who was once thought to be the 2016 front-runner, certainly won't be asking any of his supporters to "please clap" for Trump.

The 2012 Republican nominee (that was just four years ago!) won't even attend the convention. Mitt Romney, who called Trump a "phony" and a "fraud," whose promises are "worthless," a few months ago, will stay far away from Cleveland this month.

In the video above, we recap some of the most tortured excuses.
