The whole mess about Ivanka Trump's clothing line, shoe sales, and other accessories, is not about retail sales or whether or not the daughter of President Trump has a product capable of performing in the current market. Sure, Kellyanne Conway should not have plugged Ivanka's products. She holds an official government position, and she's not supposed to promote any product on the market, but she's new at this, she now knows about the ethics questions that have arisen (the Trump administration says she has been "counseled" on the issue), and she now realizes (though I think she already knew this) how far the liberal left is willing to go to politicize anything and everything they can to destroy their opposition.
The liberal left loonies have been hounding Nordstrom to drop Ivanka's products since last year. The liberal left is in such shock that their destined-to-break-the-glass-ceiling candidate, Hillary Clinton, lost the Presidential Election in 2016 that they are lashing out in a manner we have actually seen before. Trump is Hitler in the minds of the Democrats (a.k.a. Marxists, Socialists, Statists, Leftists, Utopianists, and all of the rest of the "ism" chasers), as was George W. Bush, therefore, anyone and anything associated with Donald J. Trump in any manner must be silenced, destroyed, or at least boycotted.
