Marches Might Cut Both Ways

Five Thirty Eight estimates the total number of participants in all the Saturday marches was about 3.2 million, total in the Tea Party marches of April 2009.  I can read this two ways:

• Republicans should be ten times more fearful of the passion against Trump than Democrats feared passion against Obama.  That is, the Tea Party was effective in limiting Obama to 2 years, instead of 8, so it's likely the Womens March will be more effective in limiting Trump.
• Democrats should be ten times more fearful of the passion against Trump than Republicans feared passion against Obama.  That is, the Tea Party disrupted the Republican party, moving it further to the right, so it's likely the Womens march will also move the Democratic party to the left.
