Esteemed Washington Post opinion writer George Will has done a great service to the Republican Party and contributed to the substance of the 2016 campaign by highlighting the fact that Donald Trump has not yet released his tax returns for public review and media scrutiny. Obviously, a presidential candidate releasing his or her tax returns is now standard operating procedure, confirmed by the fact that the GOP was wounded by the vicious attacks from Democrats that followed Mitt Romney’s initial refusal to release his tax returns in 2012. Well, given how frequently Trump mentions his great wealth, we can assume he won’t have any problems with making his tax returns public.

Inexplicably, none of the Republican candidates have ever really raised Trump’s tax returns as an issue. But beyond just practicing appropriate transparency in the modern era, there are serious questions the Republican Party will need to answer about how Trump plans on financing his campaign if he does win the nomination, as well as how he will coordinate with other GOP candidates and committees as the nominee.

There are already whispers coming from New York and elsewhere that Trump doesn’t have the wealth or certainly the liquidity he says he does. And so far, I can’t find any record of him talking about how he would finance a general election campaign. Will he be looking for contributions, or would he self-fund? Will he coordinate his campaign spending with other party committees to ensure they don’t suffer if his nomination disenfranchises many of the Republican Party’s core contributors? Specifically, will he bankroll the Republican National Committee and other committees? Will he kick in to support vulnerable incumbent senators? If his wealth is what he says it is, it should not be a problem.

It’s not just about the money. If Trump becomes our party’s nominee, GOP candidates on the 2016 ballot everywhere will have to determine how to orient their campaigns with the Trump campaign. How will a dignified, gracious man such as Sen. Rob Portman (R-Ohio) handle sharing the podium with crude, oafish Trump? How will an intellectually honest leader such as Sen. Pat Toomey (R-Pa.) react when confronted with Trump’s wacky, unrealistic economic plans? How will a real defense policy expert such as Sen. Kelly Ayotte (R-N.H.) handle it when she is confronted with the reality of Trump’s nonexistent knowledge of the United States’ national security challenges or military capabilities?

And oh, by the way, how will the party handle Trump’s vice-presidential nominee? Who wants to be Trump’s vice president? Could it be that we will have a “flunky” vice-presidential nominee who becomes the butt of jokes and is unwelcome at party events?

There is a lot for the GOP to consider, and it is better to ask these questions out loud now, before the Donald has a complete lock on the nomination.
