Will Hillary Clinton's election as President start the next Civil War?

It isn't as stupid as it sounds. I read online that the Tea Party is planning an Assembly of the States in 2016. With Trump's rants about immigration firing up the Republican base, and making it seem like America will topple if Hillary is elected, then I can see some of the States wanting to secede.

Is it possible for a group of states to secede in 2016, forcing the Federal Government (under Hillary Clinton) to take military action? Just wondering.
