The Democrats answer is & has been that a President Trump would not level sanctions against Russia.That in fact is their entire narrative, that Trump promised them he wouldn't place sanctions on them if they helped him get elected. Of course it is nothing more then a narrative constructed from whole cloth to create an "insurance" policy to attack Trump should the unthinkable happen, in hopes of destroying his Presidency in its infancy.
The dem narrative is made more ridiculous when you go back to Obama’s “I’ll have more flexibility after he election” remark to Medvedev just before the 2012 election...
