Ben Sasse on his way to start some dumpster fires.

Those GOP senators up for re-election this year seem to have discovered a collective need to wash their hair two weeks from now. For at least three nights. On the other hand, Republican Senators willing to share a convention hall with Donald Trump are pretty much guaranteed to be those who hope that two or so years from now, their voters will have forgotten all about this unfortunate interlude.

Of the 54 Republican senators, 16 have announced they won't be going to Cleveland and six more have yet to make a final decision.

But honestly, you have to hand it to Republicans for the list of reasons why they can’t be bothered to make an appearance to support their own party.

"Sen. Sasse will not be attending the convention and will instead take his kids to watch some dumpster fires across the state, all of which enjoy more popularity than the current front-runners,” a spokesman for Sen. Ben Sasse (R-NE) told reporters. Sen. Jeff Flake (R-AZ), who was personally attacked by Trump during a meeting with senators near Capitol Hill last week, announced he had some important household chores to attend to.“I’ve got to mow my lawn," Flake told the Associated Press.

Senators on the list of sad losers who didn’t line up for Trump include Marco Rubio, Missouri’s Roy Blunt and the suddenly Republi-phobic Mark Kirk.​

Up for re-election but still willing to climb up on stage to sing in Trump’s chorus? Ohio’s Rob Portman. Just consider him the canary in Trump Coal Mine. If Portman shows signs of life post-convention, other Republican candidates may creep closer to Trump. If Portman falls over, expect a lot of blank looks when other Republicans are asked about Donald …. who?
