Is it surprising that Soros has ties to Democratic and left-leaning organizations? Not at all.
Doesn't relegate that this is the largest protest of a President inauguration in modern history, and spawned sister protests across the globe.
I'm not sure what to tell them if they think Trump and the Republican majority in congress are going to care though. If they want to resist trump they need to get active in politics.
To be fair, I'd argue that the same could have been said about the environmental protests back in 1970 - no one expected Nixon and the Republicans to care, but they gave us the EPA and other acts that still stand today.
I'm sure that Trump and Congress won't listen today. But if anything, it unifies the people against Trump and the policies under one name - at least for today. Now we wait and see if they actually can keep that unity.
